This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

SYSTEM OVERVIEW
INTRODUCTION
The VSP5610/11/12 are analog front-end (AFE) devices for CCD and CMOS line image sensor applications such
as copiers, facsimile machines, etc. The VSP5610/11/12 each provide four independent data processing
channels.
The data from each image sensor channel are sampled and held by either the SH or CDS circuit and are then
converted into digital data by an ADC. The digital data for each channel are later converted into serial data that
can be output in either LVDS mode or CMOS mode.
AFE BLOCK
ANALOG SIGNAL INPUT
These devices have four channels that can be used as analog input ports for an image sensor. In addition to the
four-channel input, this AFE device also supports three-channel and two-channel inputs. Table 2 shows the
register settings required to select the different channel modes.
Table 2. Analog Input Channel Mode Selection

Two-channel 2 Active Standby Active Standby
Three-channel 1 Active Active Active Standby
Four-channel 0 Active Active Active Active
Each analog input supports CDS and simple SH circuits to accommodate CCD and CMOS image sensors. The
sampling mode can be selected independently for each channel by configuring the internal registers. As shown in
Table 3, if AINx_SH_CDS is set to '0', then the corresponding channel operates in CDS mode.

In addition, these devices also support independent selection of the input signal polarity for each channel. Input
signal polarity can be set using the AINx_POL register, where x = 1, 2, 3, or 4. The input signal range and
polarity are defined in the Analog Input Specification section.

Correlated Double Sampler (CDS) Mode (AINx_SH_CDS = 0)
CDS mode is designed to accommodate inputs from the CCD sensor. The output signal of a CCD image sensor
is sampled twice during one pixel period. First, the reference interval is sampled by the SHP pulse, then the data
interval is sampled by the SHD pulse. Subtracting these two samples provides the video information of the pixel
as well as removes any noise common to both intervals. Thus, CDS plays an important role in reducing the reset
noise and other low-frequency noises that are present on the CCD output signal. Figure 4 shows a diagram of
CDS mode.

Sample Hold (SH) Mode (AINx_SH_CDS = 1)
SH mode supports CCD and CMOS sensors. For the CCD sensor, the sensor signal pedestal level is clamped to
the VCLP level using an internal clamp circuit. SH samples only once during a pixel period. The SHD pulse is
used to sample the CCD signal data interval. After sampling, the SH circuit takes the difference of the data and
VCLP levels to extract the video information.
For the CMOS input, the input clamp function should be set according to the requirements. If the sensor output is
within the allowable input range, an ac-coupling capacitor for analog input may not be needed. When the sensor
signal is directly input to the AFE, the SH circuit requires a reference voltage to set the black level. To use VCLP
as a reference, SH_REFx_EN should be enabled and AINGNDx then opened or coupled to GND with a
capacitor. To use an external reference, it can be input to AINGNDx with sensor signals connected to AINx.
Figure 5 shows a diagram of the SH mode.
(1) Under some conditions, the sensor signal can be directly input to the AFE without requiring an external capacitor.
(2) In SH mode, the SHP clock should be programmed so that it does not overlap the SHD clock.
Figure 5. SH Mode Input Circuit for CCD or CMOS Signal
INPUT CLAMP AND SENSOR REFERENCE
The CCD output signal has a large dc offset that may exceed the input range of the AFE input circuit. Therefore,
this output signal is ac-coupled to the AFE through a capacitor, and the internal dc level is set to the clamp
voltage (VCLP) by an internal clamp circuit. The VSP5610/11/12 provide three modes for clamp operation: pixel
clamp, line clamp, and not clamped. These modes are shown in Table 4. The clamp mode can be set
independently for each channel by configuring the AINx_CLP_SEL register.

In pixel clamp mode, CLP_A/B is used for clamping. The input signal is clamped to VCLP via the CLP_A/B pulse
during each pixel period, as shown in Figure 6a. Because the ac-coupling capacitor is charged on a pixel-to-pixel
basis, the clamp level droop can be controlled by the clamp pulse width.
In line clamp mode, SHP_A/B is used for clamping when CLPDM is active, as shown in Figure 6b. The input
signal is clamped only in the CLPDM period within one line cycle of the sensor. The signal is clamped in this
method because the charge leaks the least from the coupling capacitor during the CLPDM period. Accordingly,
because there may be a large droop in the clamp level, this device does not support line clamp in the SH mode.
The not-clamped mode is mainly used in for a CMOS sensor input. If the sensor signal is directly connected to
the AFE, this mode should be configured without an ac-coupling capacitor at the input port. This mode has two
options to select a reference for the sensor black level: internal reference and external input. In the internal
reference option, the internal reference (VCLP) is used with AINx_CLP_SEL = 2. In the external input option, the
external input is used from AINGNDx with AINx_CLP_SEL = 3.
(1) x = AIN channel number, x = 1, 2, 3, and 4.
(2) y = Group code of sample pulse signals. When x = 1 or 2, y = A. When x = 3 or 4, y = B.

As shown in Figure 7, the internal VCLP node provides the clamp reference voltage. As for the clamp level, it is
possible to select three reference voltage modes by setting the AINx_REF_SEL register. The first mode provides
a fixed 2.2 V, the second mode provides selectable outputs (0.5 V, 1.1 V, 1.5 V, and 2.0 V) of an internal DAC,
and the third mode allows an external input from the REF_AIN pin to be used as the clamp reference. This
REF_AIN pin is bidirectional and also acts as an output of the internal DAC. Table 5 shows the relationship
between the register and clamp level. Table 6 shows the DAC configuration.
(1) If the sensor signal is directly input to the AFE, the enternal capacitor should not be connected.

If line clamp mode is used, the CLPDM period should be configured by the internal registers. The CLPDM period
is determined with reference to the line cycle signal for the sensor (LS). Thus, the start and end of CLPDM are
each defined as the number of pixels from the LS falling edge. Because CLPDM is used as the clamp period, it
should be assigned for the interval of any dummy or optical black pixels. Figure 8 shows the relationship
between LS and CLPDM.

Pixel Clamp Period Setting
In pixel clamp mode, without CLPDM, the sensor signal is clamped with CLP_A and CLP_B pulses. CLP_A
corresponds to AIN1 and AIN2; CLP_B corresponds to AIN3 and AIN4. The start of these pulses is synchronized
with the SHP_y rising edge (where y = A or B). There are two options to configure the end position: first, to
automatically set the pulse width to 50% that of SHP_y; and second, to manually configure the end position
using an internal register. Figure 9 and Figure 10 illustrate the details of the clamp pulse function in automatic
and manual modes, respectively.
Automatic Mode (CLP_TF_AT_DIS = 0)
Figure 9 shows the automatic mode when CLP_TF_AT_DIS is '0'.

Manual Mode (CLP_TF_AT_DIS = 1)

In pixel clamp mode when CLPDM is active, the sensor signal is clamped with SHP_y. Therefore, the pixel clamp
operation is closely related with the status of CLPDM. The condition of CLPDM should be properly defined with
the internal registers. Because CLPDM is always high during a default condition after reset or power up, the
status of CLPDM should be defined according to this sequence. Furthermore, the CLPDM status should be
defined in the second step of the flowchart shown in Figure 11 for either configuration. All other user-dependent
settings, except XLSYNC_SEL and EN_OUT of the software reset sequence, are described in Figure 11.
(1) Internal registers: AINx_CLP_SEL = addresses 16 and 17; LINT = address 7; DM_STR = address 8; DM_END = address 9; and

ANALOG PROGRAMMABLE GAIN (APG)
The SH output can be amplified using programmable analog gain. This gain can be set from 0.5 V/V to 3.5 V/V
with a step size of 3/64 V/V.
The gain setting can be controlled by an internal register (APG_x). Equation 1 shows the relationship between
the setting code and gain. The gain of each of the four channels can be set independently using different
registers. Note that the black pixel level may possibly change as a result of the change in the gain; therefore, the
appropriate timing of the gain change should be used to avoid degradation in image quality. Figure 12 shows
analog gain as a function of gain control code in terms of V/V. Figure 13 shows the maximum allowed input
signal as a function of gain control code.

DIGITAL PROGRAMMABLE GAIN (DPG)
The VSP5610/11/12 provide a maximum digital gain of 2 V/V. The total gain is fixed by the combination of
CDS/SH analog gain (APG) and digital gain (DPG). DPG is controlled by an 8-bit internal register (DPG_x) that
can set the gain from 1 V/V to 2 V/V, as defined by Equation 2. This register is included in each of the four
channels, so the gain of each channel can be set independently.
Figure 14 shows the relationship between the digital gain and register code. Note that the default value is 1 V/V.

TIMING GENERATOR (TG)
The image sensor timing generator (TG) is incorporated into these devices. The TG provides six signals that
function as slow transfer clocks and eight signals that function as fast transfer clocks. In addition, the fast clock
signals can also be used as slow clock signals. The TG signals are synchronized with LS (which is the image
sensor line cycle) and are completely controlled by the internal registers. Because the TG output is locked under
the default setting, EN_OUT (address 2, bit 10) should be set to '1' to enable the outputs.
LINE SYNCHRONOUS FUNCTION
The VSP5610/11/12 have two modes for synchronizing the sensor line cycle: internal line (Figure 16) and
external line syncronous mode (Figure 17). In internal line synchronous mode, the line cycle signal (LS) is
generated after a certain number of MCLK cycles that are counted by an internal counter (PIX_CNT). The
number of MCLK cycles is determined by the LINT[19:0] register; the counter clears after LS is generated. The
active LS period is equal to one MCLK cycle period.

The other mode is the external line synchronous mode which requires an external signal (XLSYNC). In this
mode, if the logic circuit detects an active XLSYNC period for more than three MCLK cycles, the internal line
synchronous signal (LS) is generated. This mode has a function that mask XLSYNC in order to avoid noise
interference. The duration of the XLSYNC mask can be set by the LINT[19:0] register, which is also used in the
internal line synchronous mode.
The two line synchronous modes and the polarity can be selected by the XLSYNC_SEL and XLSYNC_POL
registers, respectively. The default settings are external mode and active high polarity. XLSYNC can be used to
output some internal signals. Table 10 shows the register settings required to select the desired output signals.
PIX_CNT can be automatically reset by LS_CNT_RST (which is an internal register). Before performing this
function, a software reset must be executed in order set RST_ALL to '1'. If LS_CNT_RST is set to '1' after a
software reset, the pixel counter is then held at '0'. To make the counter active, LS_CNT_RST should return to
'0'.

SLOW TRANSFER CLOCK SETTING (XST, XSHn, XCLR)
XST, XSHn (where n = 1 to 4), and XCLR are slow transfer clocks that can be configured by setting the initial
polarity and toggle points. As shown in Table 11, the predetermined number of toggle points is different for each
signal. Because the two toggles generate one pulse, the number of pulses is half the number of toggles.

Each toggle position is defined by a register that is exclusive for each signal. The toggle position is synchronized
with LS and the gap between the toggle position and the LS falling edge. The LS falling edge is defined in terms
of tMCLK, the cycle period of MCLK. This gap is set by register settings and is defined by Equation 4:
t = (Xn_T(k) + 1) ×tMCLK
where:
n = ST, SHn, CLR
k = 0 to 7 (XST); k = 0 to 15 (XSHn); k = 0 to 47 (XCLR)
Xn_T(k) is less than LINT and is the register value of the toggle setting (4)
The toggle for each signal can be disabled with register settings. To make the toggle active, Xn_TGL_EN should
be set to '1'. However, because XST shares a pin with GPIO3, pin function should be configured with the
GPIO3_XST_SEL register. Figure 18 shows the configuration regarding the slow transfer clock.
(1) If Xn_Tn is set to '0', the toggle position is ignored (except for Xn_T0).
(2) The period between the toggle position and LS falling edge = (Xn_T(k) + 1) ×tMCLK.
(3) The following requirement must be satisfied: Xn_T(k) <Xn_T(k + 1).
(4) The signal is set to the desired polarity settings at the falling edge of LS.

FAST TRANSFER CLOCK PULSE SETTING
XP1/2, X1L, X2L, XRS, XCP, and XP3/4 are fast transfer clock signals with rising and falling edges that are
configurable via register settings. Figure 19 shows the block diagram of the fast clock configuration. In Figure 19,
the DLL Tap Selector is used to select both the rising and the falling edges of each signal from among 48 tap
positions.
The XP2 clock signal is an inverse of XP1 and shares rising and falling edge settings. Similarly, XP4 is an
inverse of XP3 and likewise shares rising and falling edge settings. The other signals have individual
configuration registers for setting the position of both edges.
In addition, it is possible to change the clock rate of each signal with register settings. The clock rate is based on
the frequency of MCLK. XP1 and XP2 can select x1, x2, or x4 modes with common settings. XP3 and XP4 can
also select x1, x2, or x4 modes with common settings. The other signals can choose between the x1 and x2 rate
settings.
Note that two independent sets of registers are available to set the clock rate, the clock rising edge, and the
clock falling edge for operation in x1-mode and x2-mode.

SERIAL INTERFACE
All device functions and settings are controlled through the serial interface. The serial interface consists of three
signals (SCLK, SEN, and SDI) for register writing, and a fourth signal (SDO) for readback. SDO shares the
terminal with the GPIO signal; thus, a register setting is required to activate the SDO function. Other signals are
assigned to individual terminals.
Serial data are composed of 30 bits total, as shown in Figure 25. 10 bits are assigned for the register address
and 20 bits for register data. The input serial data at SDI are sequentially stored in a shift register at the SCLK
rising edge. Data shift operation is performed at the SCLK rising edges with SEN low. All 30 input data bits are
loaded to a parallel latch in an internal register at the rising edge of SEN.
This device has two modes: read and write. The mode selection can be made via the SPL_RW internal register,
located at bit 0 of address 0. SPL_RW = 0 implies a write mode and SPL_RW = 1 implies read mode.
Figure 25. Serial I/F Data Format
WRITE MODE (SPI_RW = 0, Default)
Normally, one serial interface command is sent by one address and data combination. The address should be
sent MSB first. Data are stored into the respective register, as indicated by the address. If the serial data at the
end of the data stream are less than 30 bits, the last incomplete serial data are discarded. Figure 26 shows the
SPI signal flow while in write mode.

READ MODE (SPI_RW = 1)
In read mode, two types of connections are possible between the AFE and external systems such as an ASIC or
CPU. One connection is the four-wire connection in which the SDI and SDO pins are separately connected to the
system as shown in Figure 27a.
The other connection is a three-wire connection in which only the SDI pin is connected to the bidirectional I/O
port of the external system, as shown in Figure 27b. In this case, SDI_BUFF_CTRL should be set to '1' to create
an SPI bidirectional port. The bit flow of the four-wire connection is shown in Figure 28. The bit flow of the
three-wire connection is shown in Figure 29. As shown in Figure 29, SDI changes from an input to an output at
the SCLK falling edge after the end of the A[9:0] input. Because the SDI port is always in pull down mode, the
external pull down resistance is unnecessary.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
