Dear all

 

I use ADV7619 as a video receiver,PC->HDMI->ADV7619->TTL->FPGA,The resolution is 3840x2160@30fps,The pixel clock is 297MHz,I have produced 300 boards,Among them, more than 10 of them show abnormalities video,I used the FPGA internal logic analyzer to detect VSYNC exceptions;

 

The following picture shows the wrong video effects,Who can give some suggestions, thank you very much

 

rgds;
