The evaluation kit is based around the IDT72V283 FIFO chip from Integrated Device Technology, Inc (IDT). The system can acquire digital data at speeds up to 133 MSPS and data record lengths up to 32 kB using the HSC-ADC-EVALB-SC FIFO evaluation kit. The HSC-ADC-EVALB-DC, which has two FIFO chips, is available to evaluate multichannel ADCs or demultiplexed data from ADCs sampling faster than 133 MSPS. A USB 2.0 microcontroller communicating with ADC Analyzer allows for easy interfacing to newer computers using the USB 2.0 (USB 1.1-compatible) interface. The process of filling the FIFO chip or chips and reading the data back requires several steps. First, ADC Analyzer initiates the FIFO chip fill process. The FIFO chips are reset, using a master reset signal (MRS). The USB microcontroller is then suspended, which turns off the USB oscillator and ensures that it does not add noise to the ADC input. After the FIFO chips completely fill, the full flags from the FIFO chips send a signal to the USB microcontroller to wake up the microcontroller from suspend. ADC Analyzer waits for approximately 30 ms and then begins the readback process. During the readback process, the acquisition of data from FIFO 1 (U201) or FIFO 2 (U101) is controlled via Signal OEA and Signal OEB. Because the data outputs of both FIFO chips drive the same 16-bit data bus, the USB microcontroller controls the OEA and OEB signals to read data from the correct FIFO chip. From an application standpoint, ADC Analyzer sends commands to the USB microcontroller to initiate a read from the correct FIFO chip, or from both FIFO chips in dual or demultiplexed mode. CLOCKING DESCRIPTION Each channel of the buffer memory requires a clock signal to capture data. These clock signals are normally provided by the ADC evaluation board and are passed along with the data through Connector J104 (Pin 37 for both Channel A and Channel B). If only a single clock is passed for both channels, they can be connected together by Jumper J303. Jumpers J304 and J305 at the output of the LVDS receiver allow the output clock to be inverted by the LVDS receiver. By default, the clock outputs are inverted by the LVDS receiver. The single-ended clock signal from each data channel is buffered and converted to a differential CMOS signal by two gates of a low voltage differential signal (LVDS) receiver, U301. This allows the clock source for each channel to be CMOS, TTL, or ECL. The clock signals are ac-coupled by 0.1 F capacitors. Potentiometer R312 and Potentiometer R315 allow for fine tuning the threshold of the LVDS gates. In applications where fine-tuning the threshold is critical, these potentiometers can be replaced with a higher resistance value to increase the adjustment range. Resistors R301, R302, R303, R304, R311, R313, R314, and R316 set the static input to each of the differential gates to a dc voltage of approximately 1.5 V. At assembly, Solder Jumper J310 to Solder Jumper J313 are set to bypass the potentiometer. For fine adjustment using the pot, the solder jumpers must be removed, and R312 and R315 must be populated. U302, an XOR gate array, is included in the design to let users add gate delays to the FIFO memory chip clock paths. They are not required under normal conditions and are bypassed at assembly by Jumper J314 and Jumper J315. Jumper J306 and Jumper J307 allow the clock signals to be inverted through an XOR gate. In the default setting, the clocks are not inverted by the XOR gate. The clock paths described above determine the WRT_CLK1 and WRT_CLK2 signals at each FIFO memory chip (U101 and U201). The timing options above should let you choose a clock signal that meets the setup and hold time requirements to capture valid data. A clock generator can be applied directly to S1 and/or S3. This clock generator should be the same unit that provides the clock for the ADC. These clock paths are ac-coupled, so that a sine wave generator can be used. DC bias can be adjusted by R301/R302 and R303/R304. The DS90LV048A differential line receiver is used to square the clock signal levels applied externally to the FIFO evaluation board. The output of this clock receiver can either directly drive the write clock of the IDT72V283 FIFO(s), or first pass through the XOR gate timing circuitry described above. SPI DESCRIPTION The Cypress IC (U502) supports the HSC SPI standard to allow programming of ADCs that have SPI-accessible register maps. U102 is a buffer that drives the 4-wire SPI (SCLK, SDI, SDO, CSB 1 ) through the 120-pin connector (J104) on the third or top row. J502 is an auxiliary SPI connector to monitor the SPI signals connected directly to the Cypress IC. For more information on this and other functions, consult the user manual titled Interfacing to High Speed ADCs via SPI at www.analog.com/hsc-FIFO. 1 Note that CSB1 is the default CSB line used. Rev. 0 | Page 9 of 28 HSC-ADC-EVALB-SC/HSC-ADC-EVALB-DC The SPI interface designed on the Cypress IC can communicate with up to five different SPI-enabled devices. The CLK and data lines are common to all SPI devices. The correct device is chosen to communicate by using one of the five active low chip select pins. This functionality is controlled by selecting a SPI channel in the software. CLOCKING WITH INTERLEAVED DATA ADCs with very high data rates can exceed the capability of a single buffer memory channel (~133 MSPS). These converters often demultiplex the data into two channels to reduce the rate required to capture the data. In these applications, ADC Analyzer must interleave the data from both channels to process it as a single channel. The user can configure the software to process the first sample from Channel A, the second from Channel B, and so on, or vice versa. The synchronization circuit included in the buffer memory forces a small delay between the write enable signals (WENA and WENB) to the FIFO memory chips (Pin 1, U101, and U201), ensuring that the data is captured in one FIFO before the other. Jumper J401 and Jumper J402 determine which FIFO receives WENA and which FIFO receives WENB. CONNECTING TO THE HSC-ADC-FPGA-4/-8 ADCs that have serial LVDS outputs require another board that is connected between the ADC evaluation board and the FIFO data capture card. This board converts the serial data into parallel CMOS so that the FIFO data capture card can accept the data. For more detailed information on this board, refer to the HSC-ADC-FPGA datasheet at www.analog.com/hsc-FIFO. CONNECTING TO THE DEMUX BRD ADCs that have parallel LVDS outputs require another board that is connected between the ADC evaluation board and the FIFO data capture card. This board converts parallel LVDS to parallel CMOS, using both channels of the FIFO data capture card. For more detailed information on this board, send an email to highspeed.converters@analog.com UPGRADING FIFO MEMORY The FIFO evaluation board includes one or two 32 kB FIFOs that are capable of 133 MHz clock signals, depending on the model number.

On the FIFO evaluation board, Channel A is associated with the bottom IDT FIFO chip, and Channel B is associated with the top IDT FIFO chip (closest to the Analog Devices logo). Table 3. Jumper Legend Position In Out Position 1 or Position 3 Description Jumper in place (2-pin header). Jumper removed (2-pin header). Denotes the position of a 3-pin header. Position 1 is marked on the board. Table 4. Solder Jumper Legend Position In Out Description Solder pads should be connected with 0 resistor. Solder pads should not be connected with 0 resistor. DEFAULT SETTINGS Table 5 lists the default settings for each model of the FIFO evaluation kit. The single channel (SC) model is configured to work with a single channel ADC using the bottom FIFO, U201. The dual channel (DC) model is configured to work with demultiplexed ADCs (such as the AD9430). Dual channel ADC settings are shown in a separate column, as are settings for the opposite (top) FIFO, U101 for a single channel ADC. To align the timing properly, some evaluation boards require modifications to these settings. Refer to the Clocking Description section in the Theory of Operation section for more information. Another useful way to configure the jumper settings easily for various configurations is to consult ADC Analyzer under Help > About HSC_ADC_EVALB, and click Set Up Default Jumper Wizard. Then click the configuration setting that applies to the application of interest. A picture of the FIFO board is displayed for that application with a visual of the correct jumper settings already in place. Table 5.

This is shown in Table 5 in the jumper description column. Rev. 0 | Page 12 of 28 HSC-ADC-EVALB-SC/HSC-ADC-EVALB-DC EVALUATION BOARD The FIFO provides all of the support circuitry required to accept two channels of an ADC's digital parallel CMOS outputs. Each of the various functions and configurations can be selected by proper connection of various jumpers (see Table 5). When using this in conjunction with an ADC evaluation board, it is critical that the signal sources used for the analog input and clock have very low phase noise (<1 ps rms jitter) to realize the ultimate performance of the converter. Proper filtering of the analog input signal to remove harmonics and lower the integrated or broadband noise at the input is also necessary to achieve the specified noise performance. When operating the evaluation board in a non-default condition, J316 can be removed to disconnect the switching power supply. This enables the user to bias the board independently. Use P302 to connect an independent supply to the board. A 3.3 V supply is needed with at least a 1 A current capability. CONNECTION AND SETUP The FIFO board has a 120-pin (40-pin, triple row) connector that accepts two 16-bit channels of parallel CMOS inputs (see Figure 6). For those ADC evaluation boards that have only an 80-pin (40-pin, double row) connector, it is pertinent for the lower two rows of the FIFO's triple row connector to be connected in order for the data to pass to either FIFO channel correctly. The top or third row is used to pass SPI signals across to the adjacent ADC evaluation board that supports this feature. See Figure 5 to Figure 15 for complete schematics and layout plots. POWER SUPPLIES The FIFO board is supplied with a wall mount switching power supply that provides a 6 V, 2 A maximum output. Connect the supply to the rated 100 ac to 240 ac wall outlet at 47 Hz to 63 Hz. The other end is a 2.1 mm inner diameter jack that connects to the PCB at J301. On the PC board, the 6 V supply is then fused and conditioned before connecting to the low dropout 3.3 V linear regulator that supplies the proper bias to the entire board.

ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
