HI All,


Currently designing a module with HDMI ADV7623 chipset which will undergo EMI/EMC compliance test.

Need clarifcation on how to arrest the EMI issue on TMDS signals.


I have used  90E common mode chokes  on HDMI  TX port (Suggested in ADV7541 datasheet).

Whether this common mode chokes should be implemented in all RX ports?


Please suggest.
