WM8232
105MSPS 3-Channel AFE with Sensor
Timing Generation and LVDS/CMOS Data Output
DESCRIPTION
FEATURES
105MSPS conversion rate
16-bit ADC resolution
Current consumption – 230mA
3.3V single supply operation
The device has three analogue signal processing channels
each of which contains Reset Level Clamping, Correlated
Double Sampling (also Sample and Hold), Programmable
Gain, Automatic Gain Control (AGC) and Offset adjust
functions.
Sample and hold /correlated double sampling
Programmable offset adjust (8-bit resolution)
Flexible clamp timing
Pixel clamp / line clamp mode
Programmable clamp voltage
The output from each of these channels is time multiplexed,
in pairs, into three high-speed 16-bit Analogue to Digital
Converters. The digital data is available in a variety of
output formats via the flexible data port.
Programmable CIS/CCD timing generator
Internally generated voltage references
Compliant for Spread Spectrum Clock
The WM8232 is a 16-bit analogue front end/digitiser IC
which processes and digitises the analogue output signals
from CCD sensors or Contact Image Sensors (CIS) at pixel
sample rates of up to 35MSPS per channel.
The WM8232 has a user selectable LVDS or CMOS output
architecture.
An internal 5-bit DAC is supplied for internal reference level
generation. This may be used during CDS to reference CIS
signals or during clamping to clamp CCD signals. An
external reference level may also be supplied. ADC
references are generated internally, ensuring optimum
performance from the device.
A programmable automatic Black-Level Calibration function
is available to adjust the DC offset of the output data.
The WM8232 features a sensor timing clock generator for
both CCD and CIS sensors. The clock generator can accept
a slow or fast reference clock input and also has a flexible
timing adjustment function for output timing clocks to allow
use of many different sensors.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or
beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical
Characteristics at the test conditions specified.
ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible to
damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage of
this device.
Cirrus Logic tests its package types according to IPC/JEDEC J-STD-020 for Moisture Sensitivity to determine acceptable storage
conditions prior to surface mount assembly. These levels are:
MSL1 = unlimited floor life at <30C / 85% Relative Humidity. Not normally stored in moisture barrier bag.
MSL2 = out of bag storage for 1 year at <30C / 60% Relative Humidity. Supplied in moisture barrier bag.
MSL3 = out of bag storage for 168 hours at <30C / 60% Relative Humidity. Supplied in moisture barrier bag.
The Moisture Sensitivity Level for each package type is specified in Ordering Information.

The WM8232 includes an internal Power-On-Reset Circuit, as shown in Figure 1, which is used reset
the digital logic into a default state after power up. The POR circuit is powered from AVDD and

Figure 2 Typical Power up Sequence where AVDD is Powered before LDOOUT
Figure 2 shows a typical power-up sequence where AVDD is powered up first. When AVDD rises
above the minimum threshold, Vpora, there is enough voltage for the circuit to guarantee PORB is
asserted low and the chip is held in reset. In this condition, all writes to the control interface are
ignored. When LDOOUT rises to Vpord_on, PORB is released high and all registers are in their
default state and writes to the control interface may take place. On power down, where AVDD falls
first, PORB is asserted low whenever AVDD drops below the minimum threshold Vpora_off.

The internal control registers are programmable via the serial digital control interface. The register
contents can be read back via the serial interface on pin SDO.
It is recommended that a software reset is carried out after the power-up sequence, before writing to
any other register. This ensures that all registers are set to their default values.
DEVICE IDENTIFICATION
Up to 4 WM8232 devices can share a common set of serial interface pins. Each device on the
common interface bus must be given a different device ID. The device ID is set by the input pin
DSLCT2 and DSLCT1 as shown in Table 2.

REGISTER WRITE
Figure 4 shows the sequence of operations for performing a register write. Three pins, SCK, SDI and
SEN are used for the control interface. A 16-bit address (R/W, CS0, CS1, CS2, A11 to A0) is clocked
in through SDI, MSB first, followed by an 8 –bit data word (b7 to b0), also MSB first. Setting address
bit R/W to 0 indicates that the operation is a register write. The device ID bits (CS0 and CS1) indicate
which device is being written to on a shared control bus. A register write with CS2 set to 1 writes data
to all devices on the common bus. Each bit is latched on the rising edge of SCK. When the data has
been shifted into the device, a rising edge on the SEN pin transfers the data to the appropriate internal
register.

DEVICE DESCRIPTION
INTRODUCTION
A block diagram of the device showing the signal path is presented on the front page of this
datasheet.
The WM8232 samples up to three inputs (IN1, IN2 and IN3) simultaneously. The device then
processes the sampled video signal with respect to the video reset level or an internally/externally
generated reference level using between one and six processing channels.
Each processing channel consists of an Input Sampling block with optional Reset Level Clamping
(RLC) and Correlated Double Sampling (CDS), an 8-bit programmable offset DAC and a 12-bit
Programmable Gain Amplifier (PGA).
The ADC then converts each resulting analogue signal to a digital word. The digital output from the
ADC is presented in a variety of possible output formats in LVDS and CMOS format.
On-chip control registers determine the configuration of the device, including the offsets and gains
applied to each channel. These registers are programmable via a serial interface.
The device has an automatic Black-Level Calibration function which allows the D.C. offset determined
during the optically-black pixels at the beginning of the linear sensor to be removed during the imagepixels.
The WM8232 also has an Automatic Gain Control function which automatically adjusts the gain to an
appropriate level for a detected input level.
The device incorporates a sensor timing generation function which allows CCD and CMOS sensor
timing to be controlled directly from the device using internal clock generation and register settings.
RESET LEVEL CLAMPING (RLC)
To ensure that the signal applied to the WM8232 lies within the supply voltage range (0V to AVDD),
the output signal from a CCD is usually level shifted by coupling through a capacitor, CIN. The RLC
circuit clamps the WM8232 side of this capacitor to a suitable voltage through a CMOS switch during
the CCD reset period (pixel clamping) or during the black pixels (line clamping). In order for clamping
to produce correct results the input voltage during the clamping must be a constant value.
Note that if the A.C. coupling capacitor (CIN) is used in non-CDS mode (CDS=0), then to minimise
code drift, line clamping should be used and internal input voltage buffers enabled using the SF_INP
and SF_VRLC register bit. Alternatively, if the input signal contains a stable reference/reset level, then
pixel clamping should be used, and the voltage buffers need not be enabled.
The WM8232 allows the user to control the RLC switch in a variety of ways as illustrated in Figure 10.
This figure shows a single channel; however, all 3 channels are identical, each with its own clamp
switch controlled by the common CLMP signal.
The method of control chosen depends upon the characteristics of the input video. The VRLCEN
register bit must be set to 1 to enable clamping; otherwise, the RLC switch cannot be closed (by
default VRLCEN=1).
Note that unused inputs should be left floating, or grounded through a decoupling capacitor, if reset
level clamping is used.

Figure 10 RLC Clamp Control Options
In CDS operation, when an input waveform has a stable reference level on every pixel, it may be
desirable to clamp every pixel during this period. Setting CLAMP=high means that the RLC switch is
closed whenever the RSMP is high, as shown in Figure 11.
In non-CDS operation, setting CLAMP=high means that the RLC switch is closed whenever the VSMP
is high, as shown in Figure 12.

WM8232
CDS/NON-CDS PROCESSING
For CCD type input signals, containing a fixed reference/reset level, the signal may be processed
using Correlated Double Sampling (CDS), which will remove pixel-by-pixel common mode noise. With
CDS processing, the input waveform is sampled at two different points in time for each pixel, once
during the reference/reset level and once during the video level. To sample using CDS, register bit
CDS must be set to 1 (default = 0). This causes the signal reference to come from the video reference
level as shown in Figure 13.
For input signals that do not contain a reference/reset level (e.g. CIS sensor signals), non-CDS
processing is used (CDS=0). In this case, the video level is processed with respect to the voltage on
pin VRLC/VBIAS. The VRLC/VBIAS voltage is sampled at the same time as input samples the video
level in this mode. Note that if the A.C. coupling capacitor (CIN) is used in non-CDS mode (CDS=0),
then to minimise code drift, line clamping should be used and internal input voltage buffers enabled
using the CLPMD register bit. Alternatively, if the input signal contains a stable reference/reset level,
then pixel clamping should be used, and the voltage buffers need not be enabled.

OFFSET ADJUST AND PROGRAMMABLE GAIN
The output from the CDS block is a differential signal, which is added to the output of an 8-bit Offset
DAC to compensate for offsets and then amplified by a 12-bit PGA. The gain and offset for each
channel are independently programmable by writing to control bits DACINP[7:0] for the Offset DAC,
and AGAIN[4:0] and DGAIN[11:0] for the PGA.
The gain characteristic of the WM8232 PGA is shown in Figure 14.

The output from the PGA can be offset to match the full-scale range of the differential ADC
(1.5*[VREF1C-VREF3C]).
For negative-going input video signals, a black level (zero differential) output from the PGA should be
offset to the top of the ADC range by setting register bits PGAFS=0. For positive going input signals
the black level should be offset to the bottom of the ADC range by setting PGAFS=1.

The INPUT SAMPLING BLOCK produces an effective input voltage V1. For CDS, this is the
difference between the input video level VIN and the input reset level VRESET. For non-CDS this is the
difference between the input video level VIN and the voltage on the VRLC/VBIAS pin, VVRLC, optionally
set via the RLC DAC.
The OFFSET DAC BLOCK then adds the amount of fine offset adjustment required to move the black
level of the input signal towards 0V, producing V2.
The PGA BLOCK then amplifies the white level of the input signal to maximise the ADC range,
outputting voltage V3.
The ADC BLOCK then converts the analogue signal, V3, to a 16-bit unsigned digital output, D1.

LVDS SYNCHRONOUS OUTPUT
The LVDS synchronous output function can be used in LVDS 16-bit 5pair mode, 10-bit 3pair mode
and 12-bit 4 pair mode. In these LVDS output mode, the output data packet cycle is not same as
MCLK clock period, so that the output data at pixel counter = 0 will not be same format when the line
length is odd number.
If OUTSYNC = 1, the LVDS output format will be synchronized to pixel counter = 0.
When the line length is even number, the output data at pixel counter = 0 will be always same format,
so that the OUTSYNC is invalid. Also, the OUTSYNC is invalid in other LVDS and CMOS format. The
following shows detailed information of this mode.
Odd number line length
In odd number line length operation, the output data at pixel counter = 0 will not be same format as
shown in Figure 17. When set the OUTSYNC register, the LVDS output format will be synchronized to
pixel counter = 0 as shown in Figure 18 below.

CLOCK TIMING CONFIGURATION
The RSMP signal, VSMP signal and clock output from CLK pin are generated internally by 60 tap DLL

WM8232
SENSOR TIMING GENERATION
The WM8232 provides two types of clock internally. C_CK* are high speed clocks, these clocks can
set the clock phase by using fine pitch phase control. P_CK* are pixel rate signals which is selected
by PO0 to PO7. The WM8232 has eleven sensor TG outputs pins. CLK1 is for clock type use only.
CLK2, CLK3, CLK4, CLK5 and CLK6 are selectable high speed type signal or pulse type signal.
CLK7, CLK8, CLK9, CLK10 and CLK11 are pulse type use only.

WM8232
TG PULSE
The WM8232 can generate 8 TG pulses internally (PO0 – PO7). These pulses are generated by the
toggle point setting registers (TP*) and polarity setting registers (POL*_PO*). WM8232 provided up to
32 toggle point by using TP0 to TP31. PO0-PO7 signals can be assigned to CLK2-CLK11 by
SEL_PCK* and SEL_CLK* register.
TRIGGER DATA
The WM8232 can implement trigger data in LVDS output.(S0,S1,S2,S3 and S4) This can be selected
by two methods. One is the FLAGPIX register which can be set one pixel for each line. The other is to
apply a PO* pulse. Figure 24 shows the trigger data implementation timing.
CHANNEL ID
Also WM8232 can implement channel identification data instead of trigger data. Table 13 shows the
matrix of input channel and channel ID.

Table 13 Channel ID
Channel ID can be assigned to flag data (S0, S1, S2, S3 or S4). The following is the example of
channel ID assignment.
Example: Assigned channel ID to flag data as ID[1]=S2, ID[0]=S3.
If output data is as follows, channel ID will be IN1. (i.e. ID[1]=S2=0, ID[0]=S3=1)

TG MASK TIMING
The WM8232 has a TG clock mask function. M1, M2 and M3 pulses specify the mask period; T1 and
T2 pulses are used for changing the signal polarity during the mask period. C_CK1 and C_CK2 are
applied to the M pulse only; they cannot be applied to the T pulse. C_CK3 and C_CK4 are applied to
M1 and T1; C_CK5 and C_CK6 are applied to M2 and T2. The mask timing is synchronized with
TGCKO rise edge.

PROGRAMMABLE AUTOMATIC BLACK LEVEL CALIBRATION (BLC)
The Programmable Automatic Black-Level Calibration (BLC) function is to adjust the D.C. offset of the
output data such that the digital output code for black pixels is calibrated to a target black level value.
The D.C. offset is determined during the optically-black pixels at the beginning of the linear sensor
and removed during the image-pixels as shown in Figure 27.

Figure 27 Linear Sensor Model
The automatic black level calibration operates assuming 12 bits ADC resolution. Adjustments to
calculations must be made for different ADC resolutions.
The black level calibration process occurs in two stages as shown in Figure 28 below:
Coarse Adjust Calibration - This is a mixed signal loop which removes the coarse offset
by adjusting the offset DAC.
Fine Adjust Calibration - This is a digital loop which removes the remaining offset with
better noise tolerance, utilising ADC over-range to improve the dynamic range of the
system.

TARGET CODES
The user must specify a target black level for each channel through the registers TARGETINP*. If,
during the black-pixel period, the average ADC output code was, for example, 100 and the user
specified the target black level code to be 10, the BLC circuitry would determine 90 codes should be
subtracted from the ADC output. These 90 codes will then be subtracted from every image-pixel code
output from the ADC.
Note – changing the PGA gain affects the black-level through the device; the gain should therefore not
be changed during a BLC procedure. If the PGA gain changes, then the BLC routine should be rerun.
The automatic black level calibration feature operates with the assumption of a 12-bit ADC resolution.
The register settings for Target Codes (TARGETINP*) should be set differently depending on the ADC
42
Rev 4.6
WM8232
resolution being used. As TARGETINP* is an 8 bit register, the 4 MSBs of a data output code cannot
be changed.
16-bit ADC Resolution
For 16bit resolution the target code entered into TARGETINP* will ignore the 4 MSBs and 4 LSBs of
the 16-bit data output. For example if the desired code out is 0000111111110001, the value entered
into TARGETINP* would be 11111111.
10-bit ADC Resolution
For 10bit resolution the 4 MSBs of the 10bit data output code will be ignored. The 2 LSBs of the
target code should be set to ‘00’. For example if the desired code out is 0000111111, the value
entered into TARGETINP* would be 11111100.
BLC SCENARIOS OF OPERATION
The BLC can be used in various ways to suit the application, for example calibration can be done
once per page or once per line. Three potential scenarios of operation are suggested below.
Note: The registers FRAME_START and SEQ_START when set high by the user will automatically be
set low by the device.
SCENARIO 1
In this scenario, Coarse Adjust Calibration is enabled for the 1st line; Fine Adjust Calibration is enabled
for every line, with the Fine Adjust Calibration result recalculated every line. This scenario is suitable
for dealing with large amounts of D.C. drift throughout a frame; but this is at a cost of potential line-byline variation in the Fine Adjust result (dependent on sensor noise and the PGA gain). Table 14 shows
which registers are required for this scenario with example settings.

SCENARIO 3
In this scenario, Coarse Adjust Calibration is enabled for the 1st line; Fine Adjust Calibration is enabled
for every line, with the Fine Adjust result accumulated throughout frame and used every line. This
scenario allows any variation in the black-level to be tracked throughout the frame by accumulating
the Fine Adjust result over multiple lines. This method does not deal with as large amounts of D.C.
drift throughout the frame as scenario 1, but it will produce less line-by-line variation. Table 16 shows

Analogue Gain Calibration
The analogue gain is kept to the previous setting for (AGAIN), and the digital gain is set to x1
(DGAIN=12’d2048) automatically. During the PEAK_DET=high period, peak detection is executed and
then calculates an appropriate analogue gain (Again(N)) while PEAK_DET=low period. This period
requires at least 200 pixels. The number of peak detection cycle is selectable by the AGC_APD
register. The minimum cycle is 0 (In this case the analogue gain calibration is not executed), and the
maximum cycle is 7 lines. The peak value is cleared when the analogue peak detection finished.
Digital Gain Calibration
The analogue gain is set to the calibrated value (Again(N)), and the digital gain is set to x1
(DGAIN=12’d2048) automatically. The peak detection and digital gain calibration functions are then
executed. The number of peak detection lines is selectable by the AGC_DPD register. The minimum
cycle is 0 (In this case the digital gain calibration is not executed), and the maximum cycle is 7 lines.
Applied Calibrated Analogue and Digital Gain
The analogue and digital gain are holding calibrated value until AGC_EN register set to 0.
Again(N) = AGC_TARGETINP* / peak(n) x AGAIN

WM8232
LINE-BY-LINE OPERATION
Certain linear sensors give colour output on a line-by-line basis. i.e. a full line of red pixels followed by
a line of green pixels followed by a line of blue pixels.
The WM8232 can accommodate this type of input by setting the LINEBYLINE register bit high. The
offset and gain values that are applied to every input channel can be selected, by internal
multiplexers, to come from IN1, IN2 or IN3 offset and gain registers. This allows the gain and offset
values for each of the input colours to be setup individually at the start of a scan.
When register bit ACYC=0 the gain and offset multiplexers are controlled via the INTM[1:0] register
bits. When INTM=00 the IN1 offset and gain control registers are used to control every input channel,
INTM=01 selects the IN2 offset and gain registers and INTM=10 selects the IN3 offset and gain
registers to control every input channel.
When register bit ACYC=1, ‘auto-cycling’ is enabled, and the input channel switches to the next offset
and gain registers in the sequence by TGSYNC. The sequence is IN1 IN2 IN3 IN1… offset
and gain registers applied to every input channel.

TEST PATTERN GENERATOR
WM8232 has test pattern generator which can be used for interface verification between AFE data
output and back-end devices without sensor signal input. This function can be presented in several
different patterns by PGPAT[1:0] and PGMARCH registers as shown below. The PGLEVEL,
PGWIDTH1 and PGWIDTH2 are the parameter to define the pattern level and width. The PGLEVEL
register has 16bit length, PGWIDTH1 and PGWIDTH2 has 8bit length.
Note that test pattern generator is required TGSYNC input. (i.e. this can be used under TG slave
mode operation only.)
