Problem with ADDI7006 vga settings

Hi guys,

 

we met a very strange problem when we are using ADDI7006.

Setting registers with the vga gain (0x00 to 0x0B) affects nothing on the output,

while it seems all the other registers are okay, including the black level registers.

For example: we set cds gain from -3dB to 3dB (reg 0x19, from 0x0 to 0x4) will give a clear rise in the output data,

which result in nearly doubled.

Have any body got such experiences?

Thanks a lot for take a look on it, discussions will be appreciated.
