Hello

 

I need to configure the ADV7842 as CVBS input for PAL/NTSC/SECAM and I would like to use AGC (setting is 0x90/0x03=E4).
Although input signal is white Raster pattern, digital luma output is 0xEF/0xFF(8bit).
I need to 0xFF/0xFF(8bit) output when white siglnal is inputted.
Can I change the max value of AGC gain?

 

Thanks,
