Hello,

There're some issues for my HDMI input&output port,I'm not sure that these unstable issues caused by ADV7611(HDMI input port) or AD9889B(HDMI output port) or both.

My design is like this:HDMI source ----->ADV7611(TMDS signals are DC-Coupled)---->FPGA---->AD9889B----->screen(TMDS signals are DC-Coupled).

Is this a suitble way for ADV7611 and AD9889B or not?

Is AC-Coupled a better way for both ADV7611 and AD9889B?
