We are using AD7180 video decoder in one of our designs of analog video domain applications.     Using Hsync, Vsync and Field of Decoder, we are controlling external video Multiplexer (AD8174) for multiplexing. But, multiplexed output video has seen with flickering and we tried playing with different register settings as per the datasheet recommendations but we still see the issue. Video decoder clock out varies from 26.9Mhz to 27.01Mhz. Please provide AD7180 register settings for PAL standard if any and also we need your technical insights to address the issues.
