Hello

I am using adv7180 in a encoder project, and I use a standard decoder to return the encoder output signal, but some parameters in test result are not same as datasheet, Different gain,ChromaLum Gain and SNR. My system input is CVBS, PAL, and I set the regisiter using recommand value in datasheet, test result is : Different gain - 8% , ChromaLum Gain - 85%, SNR - 52dB, these parameters are not up to standard. Which factor may infulence these parameter?

 

I am looking forward your help.

Thanks.
