e) CTI function
f0 is selectable (1.7MHz/ 3.3MHz).
Coring level is selectable (0.4IRE/ 0.8IRE/ 1.6IRE/ 3.2IRE).
Gain is selectable (OFF/ x1/8 / x1/4 / x1/2).
f) Offset control of the period of picture area
The DC level of the Cb and Cr signals are controlled via IIC independently.
Control range : -8LSB ---- +7LSB (10bit unit)
10. Output format
Output format (data format/clock/phase) is controlled via IIC Bus.
Y:The Pedestal level is 16LSB at 8bit output format and 64LSB at 10bit output format.
C:The signal level is 128LSB except for picture periode at 8bit output mode. (10bit mode: 512LSB)
The output format (656/601) is set via FORMATO (01h,D3) and the Dynamic range is set via OUTBITS(01h、D2)
Picture periode of Y output can be controlled by CLP (20h,D0).
CLP = [1] : the signal of under 16LSB (8bit mode) is sliced at 16LSB. (standard mode.)
CLP = [0] : It’s available to output the signal of under 16LSB.
Normaly it must be set [1].
