Hi team,

could you answer the below question below.

condition

•     Do not use USB3 Down Stream, use only DP by connecting to other company's DP HDMI protocol conversion IC.

1. 
   Ifusing DP mode only, is it better to put AC coupling on the Rx side as well?
2. if so , what uF should be the multiplier?

Regards,

Shoo.
