Alternatively this port can provide Y, PB and PR signals for HDTV monitors. The SAA7104H; SAA7105H is an advanced next-generation video encoder which converts PC graphics data at maximum 1280 x 1024 resolution (optionally 1920 x 1080 interlaced) to PAL (50 Hz) or NTSC (60 Hz) video signals. A programmable scaler and anti-flicker filter (maximum 5 lines) ensures properly sized and flicker-free TV display as CVBS or S-video output. The device includes a sync/clock generator and on-chip DACs. Alternatively, the three Digital-to-Analog Converters (DACs) can output RGB signals together with a TTL composite sync to feed SCART connectors. 3 All inputs intended to interface to the host graphics controller are designed for low-voltage signals between down to 1.1 V and up to 3.6 V.

FUNCTIONAL DESCRIPTION The digital video encoder encodes digital luminance and colour difference signals (CB-Y-CR) or digital RGB signals into analog CVBS, S-video and, optionally, RGB or CR-Y-CB signals. NTSC M, PAL B/G and sub-standards are supported. The total filter transfer characteristics (scaler and anti-flicker filter are not taken into account) are illustrated in Figs 4 to 9. All three DACs are realized with full 10-bit resolution. The CR-Y-CB to RGB dematrix can be bypassed (optionally) in order to provide the upsampled CR-Y-CB input signals. The SAA7104H; SAA7105H can be directly connected to a PC video graphics controller with a maximum resolution of 1280 x 1024 (progressive) or 1920 x 1080 (interlaced) at a 50 or 60 Hz frame rate. A programmable scaler scales the computer graphics picture so that it will fit into a standard TV screen with an adjustable underscan area. Non-interlaced-to-interlaced conversion is optimized with an adjustable anti-flicker filter for a flicker-free display at a very high sharpness. The 8-bit multiplexed CB-Y-CR formats are "ITU-R BT.656" (D1 format) compatible, but the SAV and EAV codes can be decoded optionally, when the device is operated in slave mode. For assignment of the input data to the rising or falling clock edge see Tables 8 to 13. In order to display interlaced RGB signals through a euro-connector TV set, a separate digital composite sync signal (pin HSM_CSYNC) can be generated; it can be advanced up to 31 periods of the 27 MHz crystal clock in order to be adapted to the RGB processing of a TV set. Besides the most common 16-bit 4 : 2 : 2 CB-Y-CR input format (using 8 pins with double edge clocking), other CB-Y-CR and RGB formats are also supported; see Tables 8 to 13. A complete 3 x 256 bytes Look-Up Table (LUT), which can be used, for example, as a separate gamma corrector, is located in the RGB domain; it can be loaded either through the video input port PD (Pixel Data) or via the I2C-bus. The SAA7104H; SAA7105H synthesizes all necessary internal signals, colour subcarrier frequency and synchronization signals from that clock. It is also possible to connect a Philips digital video decoder (e.g. SAA7114H), using its line-locked clock for re-encoding. Information containing actual subcarrier, PAL-ID etc. is provided via pin RTCI which is connected to pin RTCO of the decoder. The SAA7104H; SAA7105H supports a 32 x 32 x 2-bit hardware cursor, the pattern of which can also be loaded through the video input port or via the I2C-bus. It is also possible to encode interlaced 4 : 2 : 2 video signals such as PC-DVD; for that the anti-flicker filter, and in most cases the scaler, will simply be bypassed. Wide screen signalling data can be loaded via the I2C-bus and is inserted into line 23 for standards using a 50 Hz field rate. Besides the applications for video output, the SAA7104H; SAA7105H can also be used for generating a kind of auxiliary VGA output, when the RGB non-interlaced input signal is fed to the DACs. This may be of interest for example, when the graphics controller provides a second graphics window at its video output port. VPS data for program dependent automatic start and stop of such featured VCRs is loadable via the I2C-bus. The IC also contains Closed Caption and extended data services encoding (line 21), and supports teletext insertion for the appropriate bit stream format at a 27 MHz clock rate (see Fig.15). It is also possible to load data for the copy generation management system into line 20 of every field (525/60 line counting). The basic encoder function consists of subcarrier generation, colour modulation and insertion of synchronization signals at a crystal-stable clock rate of 13.5 MHz (independent of the actual pixel clock used at the input side), corresponding to an internal 4 : 2 : 2 bandwidth in the luminance/colour difference domain. Luminance and chrominance signals are filtered in accordance with the standard requirements of "RS-170-A" and "ITU-R BT.470-3". 2004 Mar 04 A number of possibilities are provided for setting different video parameters such as: * Black and blanking level control * Colour subcarrier frequency * Variable burst amplitude etc. 9 Philips Semiconductors Product specification Digital video encoder 7.1 SAA7104H; SAA7105H Reset conditions If Y-CB-CR is being applied as a 27 Mbyte/s data stream, the output of the input formatter can be used directly to feed the video encoder block. To activate the reset a pulse at least of 2 crystal clocks duration is required. The horizontal upscaling is supported via the input formatter. According to the programming of the pixel clock dividers (see Section 7.10), it will sample up the data stream to 1 x, 2 x or 4 x the input data rate. An optional interpolation filter is available. The clock domain transition is handled by a 4 entries wide FIFO which gets initialized every field or explicitly at request. A bypass for the FIFO is available, especially for high input data rates. During reset (RESET = LOW) plus an extra 32 crystal clock periods, FSVGC, VSVGC, CBO, HSVGC and TTX_SRES are set to input mode and HSM_CSYNC and VSM are set to 3-state. A reset also forces the I2C-bus interface to abort any running bus transfer and sets it into receive condition. After reset, the state of the I/Os and other functions is defined by the strapping pins until an I2C-bus access redefines the corresponding registers; see Table 1. Table 1 7.3 The three 256 byte RAMs of this block can be addressed by three 8-bit wide signals, thus it can be used to build any transformation, e.g. a gamma correction for RGB signals. In the event that the indexed colour data is applied, the RAMs are addressed in parallel. Strapping pins PIN FSVGC TIED PRESET LOW NTSC M encoding, PIXCLK fits to 640 x 480 graphics input The LUTs can either be loaded by an I2C-bus write access or can be part of the pixel data input through the PD port. In the latter case, 256 x 3 bytes for the R, G and B LUT are expected at the beginning of the input video line, two lines before the line that has been defined as first active line, until the middle of the line immediately preceding the first active line. The first 3 bytes represent the first RGB LUT data, and so on. HIGH PAL B/G encoding, PIXCLK fits to 640 x 480 graphics input VSVGC LOW 4 : 2 : 2 Y-CB-CR graphics input (format 0) HIGH 4 : 4 : 4 RGB graphics input (format 3) CBO LOW input demultiplex phase: LSB = LOW 7.4 LOW input demultiplex phase: MSB = LOW HIGH input demultiplex phase: MSB = HIGH TTXRQ_XCLKO2 LOW slave (FSVGC, VSVGC and HSVGC are inputs, internal colour bar is active) The cursor bit map is set up as follows: each pixel occupies 2 bits. The meaning of these bits depends on the CMODE I2C-bus register as described in Table 4. Transparent means that the input pixels are passed through, the `cursor colours' can be programmed in separate registers. HIGH master (FSVGC, VSVGC and HSVGC are outputs) 7.2 Input formatter The bit map is stored with 4 pixels per byte, aligned to the least significant bit. So the first pixel is in bits 0 and 1, the next pixel in bits 3 and 4 and so on. The first index is the column, followed by the row; index 0,0 is the upper left corner. The input formatter converts all accepted PD input data formats, either RGB or Y-CB-CR, to a common internal RGB or Y-CB-CR data stream. When double-edge clocking is used, the data is internally split into portions PPD1 and PPD2. The clock edge assignment must be set according to the I2C-bus control bits SLOT and EDGE for correct operation. 2004 Mar 04 Cursor insertion A 32 x 32 dots cursor can be overlaid as an option; the bit map of the cursor can be uploaded by an I2C-bus write access to specific registers or in the pixel data input through the PD port. In the latter case, the 256 bytes defining the cursor bit map (2 bits per pixel) are expected immediately following the last RGB LUT data in the line preceding the first active line.

The hot spot is the `tip' of the pointer arrow. It can have any position in the bit map. The actual position registers describe the co-ordinates of the hot spot. Again 0,0 is the upper left corner. While it is not possible to move the hot spot beyond the left respectively upper screen border this is perfectly legal for the right respectively lower border. It should be noted that the cursor position is described relative to the input resolution.

The colour difference signals are fed through low-pass filters and formatted to a ITU-R BT.601 like 4 : 2 : 2 data stream for further processing. A gain adjust option corrects the level swing of the graphics world (black-to-white as 0 to 255) to the required range of 16 to 235. D0 0 CURSOR MODE 00 7.5 Cursor bit map D7 Cursor modes The matrix and formatting blocks can be bypassed for Y-CB-CR graphics input. When the auxiliary VGA mode is selected, the output of the cursor insertion block is immediately directed to the triple DAC. 7.6 Horizontal scaler The high quality horizontal scaler operates on the 4 : 2 : 2 data stream. Its control engines compensate the colour phase offset automatically. The scaler starts processing after a programmable horizontal offset and continues with a number of input pixels. Each input pixel is a programmable fraction of the current output pixel (XINC/4096). A special case is XINC = 0, this sets the scaling factor to 1. If the SAA7104H; SAA7105H input data is in accordance with "ITU-R BT.656", the scaler enters another mode. In this event, XINC needs to be set to 2048 for a scaling factor of 1. With higher values, upscaling will occur. The phase resolution of the circuit is 12 bits, giving a maximum offset of 0.2 after 800 input pixels. Small FIFOs rearrange a 4 : 2 : 2 data stream at the scaler output. 11 Philips Semiconductors Product specification Digital video encoder 7.7 SAA7104H; SAA7105H 7.10 Vertical scaler and anti-flicker filter Oscillator and Discrete Time Oscillator (DTO) The master clock generation is realized as a 27 MHz crystal oscillator, which can operate with either a fundamental wave crystal or a 3rd-harmonic crystal. The functions scaling, Anti-Flicker Filter (AFF) and re-interlacing are implemented in the vertical scaler. Besides the entire input frame, it receives the first and last lines of the border to allow anti-flicker filtering. The crystal clock supplies the DTO of the pixel clock synthesizer, the video encoder and the I2C-bus control block. It also usually supplies the triple DAC, with the exception of the auxiliary VGA or HDTV mode, where the triple DAC is clocked by the pixel clock (PIXCLK). The circuit generates the interlaced output fields by scaling down the input frames with different offsets for odd and even fields. Increasing the YSKIP setting reduces the anti-flicker function. A YSKIP value of 4095 switches it off; see Table 85. The DTO can be programmed to synthesize all relevant pixel clock frequencies between circa 40 and 85 MHz. Two programmable dividers provide the actual clock to be used externally and internally. The dividers can be programmed to factors of 1, 2, 4 and 8. For the internal pixel clock, a divider ratio of 8 makes no sense and is thus forbidden. An additional, programmable vertical filter supports the anti-flicker function. This filter is not available at upscaling factors of more than 2. The programming is similar to the horizontal scaler. For the re-interlacing, the resolutions of the offset registers are not sufficient, so the weighting factors for the first lines can also be adjusted. YINC = 0 sets the scaling factor to 1; YIWGTO and YIWGTE must not be 0. The internal clock can be switched completely to the pixel clock input. In this event, the input FIFO is useless and will be bypassed. Due to the re-interlacing, the circuit can perform upscaling by a maximum factor of 2. The maximum factor depends on the setting of the anti-flicker function and can be derived from the formulae given in Section 7.20. An additional upscaling mode allows to increase the upscaling factor to maximum 4 as it is required for the old VGA modes like 320 x 240. The entire pixel clock generation can be locked to the vertical frequency. Both pixel clock dividers get re-initialized every field. Optionally, the DTO can be cleared with each V-sync. At proper programming, this will make the pixel clock frequency a precise multiple of the vertical and horizontal frequencies. This is required for some graphic controllers. 7.8 7.11 FIFO Low-pass Clock Generation Circuit (CGC) The FIFO acts as a buffer to translate from the PIXCLK clock domain to the XTAL clock domain. The write clock is PIXCLK and the read clock is XTAL. An underflow or overflow condition can be detected via the I2C-bus read access. This block reduces the phase jitter of the synthesized pixel clock. It works as a tracking filter for all relevant synthesized pixel clock frequencies. In order to avoid underflows and overflows, it is essential that the frequency of the synthesized PIXCLK matches to the input graphics resolution and the desired scaling factor. 7.12.1 7.9 7.12 VIDEO PATH The encoder generates luminance and colour subcarrier output signals from the Y, CB and CR baseband signals, which are suitable for use as CVBS or separate Y and C signals. Border generator Input to the encoder, at 27 MHz clock (e.g. DVD), is either originated from computer graphics at pixel clock, fed through the FIFO and border generator, or a ITU-R BT.656 style signal. When the graphics picture is to be displayed as interlaced PAL, NTSC, S-video or RGB on a TV screen, it is desired in many cases not to lose picture information due to the inherent overscanning of a TV set. The desired amount of underscan area, which is achieved through appropriate scaling in the vertical and horizontal direction, can be filled in the border generator with an arbitrary true colour tint. 2004 Mar 04 Encoder 12 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H for both fields. The internal insertion window for text is set to 360 (PAL WST), 296 (NTSC WST) or 288 (NABTS) teletext bits including clock run-in bits. The protocol and timing are illustrated in Fig.15. Luminance is modified in gain and in offset (the offset is programmable in a certain range to enable different black level set-ups). A blanking level can be set after insertion of a fixed synchronization pulse tip level, in accordance with standard composite synchronization schemes. Other manipulations used for the Macrovision anti-taping process, such as additional insertion of AGC super-white pulses (programmable in height), are supported by the SAA7104H only. Alternatively, this pin can be provided with a buffered crystal clock (XCLK) of 13.5 MHz. 7.12.3 Five bytes of VPS information can be loaded via the I2C-bus and will be encoded in the appropriate format into line 16. To enable easy analog post filtering, luminance is interpolated from a 13.5 MHz data rate to a 27 MHz data rate, thereby providing luminance in a 10-bit resolution. The transfer characteristics of the luminance interpolation filter are illustrated in Figs 6 and 7. Appropriate transients at start/end of active video and for synchronization pulses are ensured. 7.12.4 The actual line number in which data is to be encoded, can be modified in a certain range. The data clock frequency is in accordance with the definition for NTSC M standard 32 times horizontal line frequency. Data LOW at the output of the DACs corresponds to 0 IRE, data HIGH at the output of the DACs corresponds to approximately 50 IRE. The amplitude (beginning and ending) of the inserted burst, is programmable in a certain range that is suitable for standard signals and for special effects. After the succeeding quadrature modulator, colour is provided on the subcarrier in 10-bit resolution. It is also possible to encode Closed Caption data for 50 Hz field frequencies at 32 times the horizontal line frequency. The numeric ratio between the Y and C outputs is in accordance with the standards. 7.12.5 ANTI-TAPING (SAA7104H ONLY) For more information contact your nearest Philips Semiconductors sales office. TELETEXT INSERTION AND ENCODING (NOT SIMULTANEOUSLY WITH REAL-TIME CONTROL) 7.13 Pin TTX_SRES receives a WST or NABTS teletext bitstream sampled at the crystal clock. At each rising edge of the output signal (TTXRQ) a single teletext bit has to be provided after a programmable delay at input pin TTX_SRES. RGB processor This block contains a dematrix in order to produce RED, GREEN and BLUE signals to be fed to a SCART plug. Before Y, CB and CR signals are de-matrixed, individual gain adjustment for Y and colour difference signals and 2 times oversampling for luminance and 4 times oversampling for colour difference signals is performed. The transfer curves of luminance and colour difference components of RGB are illustrated in Figs 8 and 9. Phase variant interpolation is achieved on this bitstream in the internal teletext encoder, providing sufficient small phase jitter on the output text lines. TTXRQ_XCLKO2 provides a fully programmable request signal to the teletext source, indicating the insertion period of bitstream at lines which can be selected independently 2004 Mar 04 CLOSED CAPTION ENCODER Using this circuit, data in accordance with the specification of Closed Caption or extended data service, delivered by the control interface, can be encoded (line 21). Two dedicated pairs of bytes (two bytes per field), each pair preceded by run-in clocks and framing code, are possible. Chrominance is modified in gain (programmable separately for CB and CR), and a standard dependent burst is inserted, before baseband colour signals are interpolated from a 6.75 MHz data rate to a 27 MHz data rate. One of the interpolation stages can be bypassed, thus providing a higher colour bandwidth, which can be used for the Y and C output. The transfer characteristics of the chrominance interpolation filter are illustrated in Figs 4 and 5. 7.12.2 VIDEO PROGRAMMING SYSTEM (VPS) ENCODING 13 Philips Semiconductors Product specification Digital video encoder 7.14 SAA7104H; SAA7105H In slave mode, the circuit accepts sync pulses on the bidirectional FSVGC (frame sync), VSVGC (vertical sync) and HSVGC (horizontal sync) pins: the polarities of the signals can be programmed. The frame sync signal is only necessary when the input signal is interlaced, in other cases it may be omitted. If the frame sync signal is present, it is possible to derive the vertical and the horizontal phase from it by setting the HFS and VFS bits. HSVGC and VSVGC are not necessary in this case, so it is possible to switch the pins to output mode. Triple DAC Both Y and C signals are converted from digital-to-analog in a 10-bit resolution at the output of the video encoder. Y and C signals are also combined into a 10-bit CVBS signal. The CVBS output signal occurs with the same processing delay as the Y, C and optional RGB or CR-Y-CB outputs. Absolute amplitude at the input of the DAC for CVBS is reduced by 1516 with respect to Y and C DACs to make maximum use of the conversion ranges. Alternatively, the device can be triggered by auxiliary codes in a ITU-R BT.656 data stream via PD7 to PD0. RED, GREEN and BLUE signals are also converted from digital-to-analog, each providing a 10-bit resolution. Only vertical frequencies of 50 and 60 Hz are allowed with the SAA7104H; SAA7105H. In slave mode, it is not possible to lock the encoders colour carrier to the line frequency with the PHRES bits. The reference currents of all three DACs can be adjusted individually in order to adapt for different output signals. In addition, all reference currents can be adjusted commonly to compensate for small tolerances of the on-chip band gap reference voltage. In the (more common) master mode, the time base of the circuit is continuously free-running. The IC can output a frame sync at pin FSVGC, a vertical sync at pin VSVGC, a horizontal sync at pin HSVGC and a composite blanking signal at pin CBO. All of these signals are defined in the PIXCLK domain. The duration of HSVGC and VSVGC are fixed, they are 64 clocks for HSVGC and 1 line for VSVGC. The leading slopes are in phase and the polarities can be programmed. Alternatively, all currents can be switched off to reduce power dissipation. All three outputs can be used to sense for an external load (usually 75 ) during a pre-defined output. A flag in the I2C-bus status byte reflects whether a load is applied or not. In addition, an automatic sense mode can be activated which indicates a 75 load at any of the three outputs at the dedicated interrupt pin TVD. The input line length can be programmed. The field length is always derived from the field length of the encoder and the pixel clock frequency that is being used. If the SAA7104H; SAA7105H is required to drive a second (auxiliary) VGA monitor or an HDTV set, the DACs receive the signal coming from the HD data path. In this event, the DACs are clocked at the incoming PIXCLKI instead of the 27 MHz crystal clock used in the video encoder. 7.15 CBO acts as a data request signal. The circuit accepts input data at a programmable number of clocks after CBO goes active. This signal is programmable and it is possible to adjust the following (see Figs 13 and 14): HD data path * The horizontal offset This data path allows the SAA7104H; SAA7105H to be used with VGA or HDTV monitors. It receives its data directly from the cursor generator and supports RGB and Y-PB-PR output formats (RGB not with Y-PB-PR input formats). No scaling is done in this mode. * The length of the active part of the line A gain adjustment either leads the full level swing to the digital-to-analog converters or reduces the amplitude by a factor of 0.69. This enables sync pulses to be added to the signal as it is required for display units expecting signals with sync pulses, either regular or 3-level syncs. In most cases, the vertical offsets for odd and even fields are equal. If they are not, then the even field will start later. The SAA7104H; SAA7105H will also request the first input lines in the even field, the total number of requested lines will increase by the difference of the offsets. 7.16 * The distance from active start to first expected data * The vertical offset separately for odd and even fields * The number of lines per input field. As stated above, the circuit can be programmed to accept the look-up and cursor data in the first 2 lines of each field. The timing generator provides normal data request pulses for these lines; the duration is the same as for regular lines. Timing generator The synchronization of the SAA7104H; SAA7105H is able to operate in two modes; slave mode and master mode. 2004 Mar 04 14 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H The additional request pulses will be suppressed with LUTL set to logic 0; see Table 108. The other vertical timings do not change in this case, so the first active line can be number 2, counted from 0. 7.17 image, the lines as well as fractions of lines. Figure 3 illustrates the context between the various tables. The first table serves as an array to hold the correct sequence of lines that compose the synchronization raster; it can contain up to 16 entries. Each entry holds a 4-bit index to the next table and a 10-bit counter value which specifies how often this particular line is invoked. If the necessary line count for a particular line exceeds the 10 bits, it has to use two table entries. Pattern generator for HD sync pulses The pattern generator provides appropriate synchronization patterns for the video data path in auxiliary monitor or HDTV mode. It provides maximum flexibility in terms of raster generation for all interlaced and non-interlaced computer graphics or ATSC formats. The sync engine is capable of providing a combination of event-value pairs which can be used to insert certain values in the outgoing data stream at specified times. It can also be used to generate digital signals associated with time events. These can be used as digital horizontal and vertical synchronization signals on pins HSM_CSYNC and VSM. The 4-bit index in the line count array points to the line type array. It holds up to 15 entries (index 0 is not used), index 1 points to the first entry, index 2 to the second entry of the line type array etc. Each entry of the line type array can hold up to 8 index pointers to another table. These indices point to portions of a line pulse pattern: A line could be split up e.g. into a sync, a blank, and an active portion followed by another blank portion, occupying four entries in one table line. The picture position is adjustable through the programmable relationship between the sync pulses and the video contents. Each index of this table points to a particular line of the next table in the linked list. This table is called the line pattern array and each of the up to seven entries stores up to four pairs of a duration in pixel clock cycles and an index to a value table. The table entries are used to define portions of a line representing a certain value for a certain number of clock cycles. The generation of embedded analog sync pulses is bound to a number of events which can be defined for a line. Several of these line timing definitions can exist in parallel. For the final sync raster composition a certain sequence of lines with different sync event properties has to be defined. The sequence specifies a series of line types and the number of occurrences of this specific line type. Once the sequence has been completed, it restarts from the beginning. All pulse shapes are filtered internally in order to avoid ringing after analog post filters. The value specified in this table is actually another 3-bit index into a value array which can hold up to eight 8-bit values. If bit 4 (MSB) of the index is logic 1, the value is inserted into the G or Y signal, only; if bit 4 = 0, the associated value is inserted into all three signals. The sequence of the generated pulse stream must fit precisely to the incoming data stream in terms of the total number of pixels per line and lines per frame. Two additional bits of the entries in the value array (LSBs of the second byte) determine if the associated events appear as a digital pulse on the HSM_CSYNC and/or VSM outputs. The sync engines flexibility is achieved by using a sequence of linked lists carrying the properties for the 2004 Mar 04 15 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ... 10-bit line count line count pointer LINE COUNT ARRAY 16 entries line type pointer 3 3 3 3 3 3 3 3 pattern pointer LINE TYPE ARRAY 15 entries 16 3 3 3 3 3 Philips Semiconductors 4-bit line type index Digital video encoder 2004 Mar 04 handbook, full pagewidth 3 3 3 event type pointer 8 + 2-bit value 10-bit duration 10-bit duration 10-bit duration 4-bit value index 4-bit value index 4-bit value index 4-bit value index LINE PATTERN ARRAY 7 entries line pattern pointer MHC573 Product specification Fig.3 Context between the pattern generator tables for DH sync pulses. SAA7104H; SAA7105H VALUE ARRAY 8 entries 10-bit duration Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H To ease the trigger set-up for the sync generation module, a set of registers is provided to set up the screen raster which is defined as width and height. A trigger position can be specified as an x,y co-ordinate within the overall dimensions of the screen raster. If the x,y counter matches the specified co-ordinates, a trigger pulse is generated which pre-loads the tables with their initial values. Important note: Due to a problem in the programming interface, writing to the line pattern array (address D2) might destroy the data of the line type array (address D1). A work around is to write the line pattern array data before writing the line type array. Reading of the arrays is possible but all address pointers must be initialized before the next write operation. The listing in Table 5 outlines an example on how to set up the sync tables for a 1080i HD raster.

If there is no pixel clock, the IC is not able to set its outputs to LOW. So, in most cases, DOWNA and DOWND should be set to logic 1 simultaneously. If the EIDIV bit is logic 1, it should be set to logic 0 before power-down. I2C-bus interface The I2C-bus interface is a standard slave transceiver, supporting 7-bit slave addresses and 400 kbits/s guaranteed transfer rate. It uses 8-bit subaddressing with an auto-increment function. All registers are write and read, except two read only status bytes. The register bit map consists of an RGB Look-Up Table (LUT), a cursor bit map and control registers. The LUT contains three banks of 256 bytes, where each RGB triplet is assigned to one address. Thus a write access needs the LUT address and three data bytes following subaddress FFH. For further write access auto-incrementing of the LUT address is performed. The cursor bit map access is similar to the LUT access but contains only a single byte per address. 7.20 The SAA7104H; SAA7105H needs to provide a continuous data stream at its analog outputs as well as receive a continuous stream of data from its data source. Because there is no frame memory isolating the data streams, restrictions apply to the input frame timings. Input and output processing of the SAA7104H; SAA7105H are only coupled through the vertical frequencies. In master mode, the encoder provides a vertical sync and an odd/even pulse to the input processing. In slave mode, the encoder receives them. The I2C-bus slave address is defined as 88H. 7.19 Power-down modes In order to reduce the power consumption, the SAA7104H; SAA7105H supports 2 power-down modes, accessible via the I2C-bus. The analog power-down mode (DOWNA = 1) turns off the digital-to-analog converters and the pixel clock synthesizer. The digital power-down mode turns off all internal clocks and sets the digital outputs to LOW except the I2C-bus interface. The IC keeps its programming and can still be accessed in this mode, however not all registers can be read or written to. Reading or writing to the look-up tables, the cursor and the HD sync generator require a valid pixel clock. The typical supply current in full power-down is approximately 5 mA. 2004 Mar 04 Programming the SAA7104H; SAA7105H The parameters of the input field are mainly given by the memory capacity of the SAA7104H; SAA7105H. The rule is that the scaler and thus the input processing needs to provide the video data in the same time frames as the encoder reads them. Therefore, the vertical active video times (and the vertical frequencies) need to be the same. The second rule is that there has to be data in the buffer FIFO when the encoder enters the active video area. Therefore, the vertical offset in the input path needs to be a bit shorter than the offset of the encoder. 18 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H The following Sections give the set of equations required to program the IC for the most common application: A post processor in master mode with non-interlaced video input data. The required pixel clock frequency can be determined in the following way: Due to the limited internal FIFO size, the input path has to provide all pixels in the same time frame as the encoders vertical active time. The scaler also has to process the first and last border lines for the anti-flicker function. Thus: 262.5 x 1716 x TXclk TPclk = ---------------------------------------------------------------------------------------- (60 Hz) InLin + 2 InPpl x integer ---------------------- x 262.5 OutLin Some variables are defined below: * InPix: the number of active pixels per input line * InPpl: the length of the entire input line in pixel clocks * InLin: the number of active lines per input field/frame * TPclk: the pixel clock period 312.5 x 1728 x TXclk TPclk = ---------------------------------------------------------------------------------------- (50 Hz) InLin + 2 InPpl x integer ---------------------- x 312.5 OutLin * RiePclk: the ratio of internal to external pixel clock * OutPix: the number of active pixels per output line and for the pixel clock generator TXclk 20 + PCLE PCL = --------------- x 2 (all frequencies); TPclk see Tables 67, 69 and 70. The divider PCLE should be set according to Table 69. PCLI may be set to a lower or the same value. Setting a lower value means that the internal pixel clock is higher and the data get sampled up. The difference may be 1 at 640 x 480 pixels resolution and 2 at resolutions with 320 pixels per line as a rule of thumb. This allows horizontal upscaling by a maximum factor of 2 respectively 4 (this is the parameter RiePclk). * OutLin: the number of active lines per output field * TXclk: the encoder clock period (37.037 ns). 7.20.1 TV DISPLAY WINDOW At 60 Hz, the first visible pixel has the index 256, 710 pixels can be encoded; at 50 Hz, the index is 284, 702 pixels can be visible. The output lines should be centred on the screen. It should be noted that the encoder has 2 clocks per pixel; see Table 58. log RiePclk PCLI = PCLE - ---------------------------- (all frequencies) log 2 ADWHS = 256 + 710 - OutPix (60 Hz); ADWHS = 284 + 702 - OutPix (50 Hz); ADWHE = ADWHS + OutPix x 2 (all frequencies) The equations ensure that the last line of the field has the full number of clock cycles. Many graphic controllers require this. Note that the bit PCLSY needs to be set to ensure that there is not even a fraction of a clock left at the end of the field. For vertical, the procedure is the same. At 60 Hz, the first line with video information is number 19, 240 lines can be active. For 50 Hz, the numbers are 23 and 287; see Table 64. 240 - OutLin FAL = 19 + --------------------------------- (60 Hz); 2 7.20.3 XOFS can be chosen arbitrarily, the condition being that XOFS + XPIX HLEN is fulfilled. Values given by the VESA display timings are preferred. 287 - OutLin FAL = 23 + --------------------------------- (50 Hz); 2 LAL = FAL + OutLin (all frequencies) HLEN = InPpl x RiePclk - 1 InPix XPIX = ------------- x RiePclk 2 Most TV sets use overscan, and not all pixels respectively lines are visible. There is no standard for the factor, it is highly recommended to make the number of output pixels and lines adjustable. A reasonable underscan factor is 10%, giving approximately 640 output pixels per line. 7.20.2 4096 OutPix XINC = ------------------ x -------------------InPix RiePclk XINC needs to be rounded up, it needs to be set to 0 for a scaling factor of 1. INPUT FRAME AND PIXEL CLOCK The total number of pixel clocks per line and the input horizontal offset need to be chosen next. The only constraint is that the horizontal blanking has at least 10 clock pulses. 2004 Mar 04 HORIZONTAL SCALER 19 Philips Semiconductors Product specification Digital video encoder 7.20.4 SAA7104H; SAA7105H Or the upscaling factor needs to be limited to 1.5 and the horizontal upscaling factor is also limited to less than 1.5. In this case a normal blanking length is sufficient. VERTICAL SCALER The input vertical offset can be taken from the assumption that the scaler should just have finished writing the first line when the encoder starts reading it: FAL x 1716 x TXclk YOFS = ---------------------------------------------------- - 2.5 (60 Hz) InPpl x TPclk 7.21 Input levels and formats The SAA7104H; SAA7105H accepts digital Y, CB, CR or RGB data with levels (digital codes) in accordance with "ITU-R BT.601". An optional gain adjustment also allows to accept data with the full level swing of 0 to 255. FAL x 1728 x TXclk YOFS = ---------------------------------------------------- - 2.5 (50 Hz) InPpl x TPclk In most cases the vertical offsets will be the same for odd and even fields. The results should be rounded down. For C and CVBS outputs, deviating amplitudes of the colour difference signals can be compensated for by independent gain control setting, while gain for luminance is set to predefined values, distinguishable for 7.5 IRE set-up or without set-up. YPIX = InLin YSKIP defines the anti-flicker function. 0 means maximum flicker reduction but minimum vertical bandwidth, 4095 gives no flicker reduction and maximum bandwidth. Note that the maximum value for YINC is 4095. It might be necessary to reduce the value of YSKIP to fulfil this requirement. The RGB, respectively CR-Y-CB path features an individual gain setting for luminance (GY) and colour difference signals (GCD). Reference levels are measured with a colour bar, 100% white, 100% amplitude and 100% saturation. OutLin YSKIP YINC = ---------------------- x 1 + ----------------- x 4096 InLin + 2 4095 The SAA7104H; SAA7105H has special input cells for the VGC port. They operate at a wider supply voltage range and have a strict input threshold at 1/2VDDD. To achieve full speed of these cells, the EIDIV bit needs to be set to logic 1. Note that the impedance of these cells is approximately 6 k. This may cause trouble with the bootstrapping pins of some graphic chips. So the power-on reset forces the bit to logic 0, the input impedance is regular in this mode. YINC YIWGTO = -------------- + 2048 2 YINC - YSKIP YIWGTE = -------------------------------------2 When YINC = 0 it sets the scaler to scaling factor 1. The initial weighting factors must not be set to 0 in this case. YIWGTE may go negative. In this event, YINC should be added and YOFSE incremented. This can be repeated as often as necessary to make YIWGTE positive. Table 6 "ITU-R BT.601" signal component levels SIGNALS(1) It should be noted that these equations assume that the input is non-interlaced but the output is interlaced. If the input is interlaced, the initial weighting factors need to be adapted to obtain the proper phase offsets in the output frame. COLOUR If vertical upscaling beyond the upper capabilities is required, the parameter YUPSC may be set to logic 1. This extends the maximum vertical scaling factor by a factor of 2. Only the parameter YINC is affected, it needs to be divided by two to get the same effect.

The value defines the time in pixel clocks (HPD + 1) the corresponding value HPV is added to the HD output signal. If 0, this entry will be skipped. HPV HD pattern value pointer. This gives the index in the HD value array containing the level to be inserted into the HD output path. If the MSB of HPV is logic 1, the value will only be inserted into the Y/GREEN channel of the HD data path, the other channels remain unchanged. 2004 Mar 04 45 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H Table 93 Layout of the data bytes in the line pattern array BYTE DESCRIPTION 0 HPD07 HPD06 HPD05 HPD04 HPD03 HPD02 HPD01 HPD00 1 HPV03 HPV02 HPV01 HPV00 0 0 HPD09 HPD08 2 HPD17 HPD16 HPD14 HPD14 HPD13 HPD12 HPD11 HPD10 3 HPV13 HPV12 HPV11 HPV10 0 0 HPD19 HPD18 4 HPD27 HPD26 HPD25 HPD24 HPD23 HPD22 HPD21 HPD20 5 HPV23 HPV22 HPV21 HPV20 0 0 HPD29 HPD28 6 HPD37 HPD36 HPD35 HPD34 HPD33 HPD32 HPD31 HPD30 7 HPV33 HPV32 HPV31 HPV30 0 0 HPD39 HPD38 Table 94 Subaddress D3H DATA BYTE DESCRIPTION HPVA RAM start address for the HD sync value array; the byte following subaddress D3 points to the first cell to be loaded with the next transmitted byte; succeeding cells are loaded by auto-incrementing until stop condition.

Details about the JTAG BST-TEST can be found in the specification "IEEE Std. 1149.1". A file containing the detailed Boundary Scan Description Language (BSDL) of the SAA7104H; SAA7105H is available on request. The SAA7104H; SAA7105H has built-in logic and 5 dedicated pins to support boundary scan testing which allows board testing without special hardware (nails). The SAA7104H; SAA7105H follows the "IEEE Std. 1149.1 Standard Test Access Port and Boundary-Scan Architecture" set by the Joint Test Action Group (JTAG) chaired by Philips. The 5 special pins are Test Mode Select (TMS), Test Clock (TCK), Test Reset (TRST), Test Data Input (TDI) and Test Data Output (TDO). Table 115 BST instructions supported by the SAA7104H; SAA7105H INSTRUCTION 8.1 DESCRIPTION BYPASS This mandatory instruction provides a minimum length serial path (1 bit) between TDI and TDO when no test operation of the component is required. EXTEST This mandatory instruction allows testing of off-chip circuitry and board level interconnections. SAMPLE This mandatory instruction can be used to take a sample of the inputs during normal operation of the component. It can also be used to preload data values into the latched outputs of the boundary scan register. CLAMP This optional instruction is useful for testing when not all ICs have BST. This instruction addresses the bypass register while the boundary scan register is in external test mode. IDCODE This optional instruction will provide information on the components manufacturer, part number and version number. INTEST This optional instruction allows testing of the internal logic (no support for customer available). USER1 This private instruction allows testing by the manufacturer (no support for customer available). Initialization of boundary scan circuit When the IDCODE instruction is loaded into the BST instruction register, the identification register will be connected between TDI and TDO of the IC. The identification register will load a component specific code during the CAPTURE_DATA_REGISTER state of the TAP controller, this code can subsequently be shifted out. At board level this code can be used to verify component manufacturer, type and version number. The device identification register contains 32 bits, numbered 31 to 0, where bit 31 is the most significant bit (nearest to TDI) and bit 0 is the least significant bit (nearest to TDO); see Fig.10. The Test Access Port (TAP) controller of an IC should be in the reset state (TEST_LOGIC_RESET) when the IC is in functional mode. This reset state also forces the instruction register into a functional instruction such as IDCODE or BYPASS. To solve the power-up reset, the standard specifies that the TAP controller will be forced asynchronously to the TEST_LOGIC_RESET state by setting the TRST pin LOW. 8.2 Device identification codes A device identification register is specified in "IEEE Std. 1149.1b-1994". It is a 32-bit register which contains fields for the specification of the IC manufacturer, the IC part number and the IC version number. Its biggest advantage is the possibility to check for the correct ICs mounted after production and to determine the version number of the ICs during field service. 2004 Mar 04 53 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H MSB handbook, full pagewidth 31 TDI LSB 28 27 12 11 1 0101 0111000100000100 00000010101 4-bit version code 16-bit part number 11-bit manufacturer identification 31 TDI TDO 1 MHC568 a.

The overall Rth(j-a) value can vary depending on the board layout. To minimize the effective Rth(j-a) all power and ground pins must be connected to the power and ground layers directly. An ample copper area direct under the SAA7104H; SAA7105H with a number of through-hole plating, which connect to the ground layer (four-layer board: second layer), can also reduce the effective Rth(j-a). Please do not use any solder-stop varnish under the chip.

The insertion window is not opened if the control bit TTXEN is zero. Teletext timing Time tFD is the time needed to interpolate input data TTX and insert it into the CVBS and VBS output signal, such that it appears at tTTX = 9.78 s (PAL) or tTTX = 10.5 s (NTSC) after the leading edge of the horizontal synchronization pulse. Time tPD is the pipeline delay time introduced by the source that is gated by TTXRQ_XCLKO2 in order to deliver TTX data. This delay is programmable by register TTXHD. For every active HIGH state at output pin TTXRQ_XCLKO2, a new teletext bit must be provided by the source. Using appropriate programming, all suitable lines of the odd field (TTXOVS and TTXOVE) plus all suitable lines of the even field (TTXEVS and TTXEVE) can be used for teletext insertion. It is essential to note that the two pins used for teletext insertion must be configured for this purpose by the correct I2C-bus register settings. Since the beginning of the pulses representing the TTXRQ signal and the delay between the rising edge of TTXRQ and valid teletext input data are fully programmable (TTXHS and TTXHD), the TTX data is always inserted at the correct position after the leading edge of the outgoing horizontal synchronization pulse. handbook, full pagewidth CVBS/Y t TTX text bit #: 1 t i(TTXW) 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 TTX_SRES t PD t FD TTXRQ_XCLKO2 MHB891 Fig.15 Teletext timing. 2004 Mar 04 61 24 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H 12 APPLICATION INFORMATION DVO handbook, full pagewidth supply 0.1 F +3.3 V digital supply 0.1 F DGND +3.3 V analog supply AGND 10 pF use one capacitor for each VDDD VDDD1 6 0.1 F 1 nF DGND 0.1 H AGND 10 pF use one capacitor for each VDDA 27 MHz VDDD2 to VDDD4 XTALI XTALO VDDA1 to VDDA3 12, 25, 53 51 50 43, 44, 52 39, 40 VSM, HSM_CSYNC GREEN_VBS_CVBS 42 FLTR0 75 75 AGND AGND UY AGND RED_CR_C_CVBS SAA7104H SAA7105H digital inputs and outputs 41 FLTR1 75 75 AGND AGND UC AGND BLUE_CB_CVBS 45 FLTR2 75 7, 13, 26, 57 48 46 47 VSSD1 to VSSD4 VSSA RSET DUMP AGND AGND AGND Fig.16 Application circuit. 2004 Mar 04 62 AGND UCVBS AGND 12 1 k DGND AGND 75 MHC686 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H C16 handbook, halfpage 120 pF L2 L3 2.7 H 2.7 H C10 390 pF C13 560 pF AGND JP11 JP12 FIN FOUT FILTER 1 = byp. ll act.

Figure 17 shows a possible reconstruction filter for the digital-to-analog converters. Due to its cut-off frequency of 6 MHz, it is not suitable for HDTV applications. 12.2 By setting the reference currents of the DACs as shown in Table 116, standard compliant amplitudes can be achieved for all signal combinations; it is assumed that in subaddress 16H, parameter DACF = 0000b, that means the fine adjustment for all DACs in common is set to 0%. Analog output voltages The analog output voltages are dependent on the total load (typical value 37.5 ), the digital gain parameters and the I2C-bus settings of the DAC reference currents (analog settings). If S-video output is desired, the adjustment for the C (chrominance subcarrier) output should be identical to the one for VBS (luminance plus sync) output.

Place the analog termination resistors close to the coupling capacitors. Use separate ground planes for analog and digital ground. Connect these planes only at one point directly under the device, by using a 0 resistor directly at the supply stage. Use separate supply lines for analog and digital supply. Place the supply decoupling capacitors close to the supply pins. Be careful of hidden layout capacitors around the crystal application. Use serial resistors in clock, sync and data lines, to avoid clock or data reflection effects and to soften data energy. Use Lbead (ferrite coil) in each digital supply line close to the decoupling capacitors to minimize radiation energy (EMC). 2004 Mar 04 RGB, BLACK-TO-WHITE 65 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H 13 PACKAGE OUTLINE QFP64: plastic quad flat package; 64 leads (lead length 1.6 mm); body 14 x 14 x 2.7 mm SOT393-1 c y X A 48 33 49 32 ZE e E HE A A2 (A 3) A1 wM pin 1 index Lp bp L 17 64 detail X 16 1 w M bp e v M A ZD D B HD v M B 0 5 10 mm scale DIMENSIONS (mm are the original dimensions) UNIT A max.

A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 14.2 - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. Reflow soldering The footprint must incorporate solder thieves at the downstream end. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical reflow peak temperatures range from 215 to 270 C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. * below 225 C (SnPb process) or below 245 C (Pb-free process) A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. - for all BGA, HTSSON-T and SSOP-T packages 14.4 - for packages with a thickness 2.5 mm Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. - for packages with a thickness < 2.5 mm and a volume 350 mm3 so called thick/large packages. * below 240 C (SnPb process) or below 260 C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 14.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. 2004 Mar 04 Manual soldering 67 Philips Semiconductors Product specification Digital video encoder 14.5 SAA7104H; SAA7105H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE REFLOW(2) BGA, HTSSON..T(3), LBGA, LFBGA, SQFP, SSOP..T(3), TFBGA, USON, VFBGA not suitable suitable DHVQFN, HBCC, HBGA, HLQFP, HSO, HSOP, HSQFP, HSSON, HTQFP, HTSSOP, HVQFN, HVSON, SMS not suitable(4) suitable PLCC(5), SO, SOJ suitable suitable not recommended(5)(6) suitable SSOP, TSSOP, VSO, VSSOP not recommended(7) suitable CWQCCN..L(8), PMFP(9), WQCCN..L(8) not suitable LQFP, QFP, TQFP not suitable Notes 1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 C 10 C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. 4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. 9. Hot bar or manual soldering is suitable for PMFP packages. 2004 Mar 04 68 Philips Semiconductors Product specification Digital video encoder SAA7104H; SAA7105H 15 DATA SHEET STATUS LEVEL DATA SHEET STATUS(1) PRODUCT STATUS(2)(3) Development DEFINITION I Objective data II Preliminary data Qualification This data sheet contains data from the preliminary specification.
