Figure 6 Reset Sample and Clamp Timing
For CIS type sensor signals, non-CDS processing is used. In this case, the video level is processed
with respect to the voltage on pin VRLC/VBIAS, generated internally or externally as described
above. The VRLC/VBIAS pin is sampled by R
s
at the same time as V
s
samples the video level in this
mode.
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 an 8-bit PGA. The gain and offset can be set
for each of three colours by writing to control bits DACx[7:0] and PGAx[7:0] (where x can be R, G or
B).
In colour line-by-line mode the gain and offset coefficients that are applied to the PGA and offset
DAC can be multiplexed by control of the INTM[1:0] bits as shown in Table 1.

DESCRIPTION
Red offset and gain registers are applied to offset DAC and PGA
(DACR[7:0] and PGAR[7:0])
Green offset and gain registers applied to offset DAC and PGA
(DACG[7:0] and PGAG[7:0])
Blue offset and gain registers applied to offset DAC and PGA
(DACB[7:0] and PGAB[7:0])
Reserved.

The gain characteristic of the WM8150 PGA is shown in Figure 7. Figure 8 shows the maximum
input voltage (at VINP) that can be gained up to match the ADC full-scale input range (2.5V).
