On our ADV7612 board we had to change the equalizer settings since the output was not stable with the recommended register values.
This was probably due to a schematic or layout issue on our board.
We are now redesigning this board and are able to change the schematic and layout. We would like to know what points should be examined/reworked in order to improve our board behaviour and be able to get stable output with recommended equalizer register values.
FIY the TMDS traces seem to be OK since they are very short and well 100 ohms balanced routed between the connector and the ADV7612 part.
