When using YCbCr mode, it is cautious of the input level to CAD (color system 8bit AD).
As shown in Fig-2, the standard input level of the CAD is 0.7Vp-p.
c) Clamping
The clamp control circuit controls the correct clamping of the analog input signals.
Clamp level for CVBS and Y signal is 256 LSB (10bit unit). For C and Cb/Cr are 128 LSB (8bit unit).
Cb and Cr signals are multiplexed in front of internal 8bit ADC.
Offset adjustment is available independently.
