Hi Torsten:

    AUX signal is 3.3v,  SN65MLVD203B is LVDS device which may not  support 3.3v signal.

   Please submit another thread with any DP device, which will goes to Ethernet /DP group.

Hi Brian,

This related question SN74LVC2G125: Displayport AUX channel buffer - Logic forum - Logic - TI E2E support forums 

is marked in the task below with a note to look here for driving and receiving AUX signals:
www.ti.com/.../lvds-phy-less-than-800-mbps-products.page
When I search there and enter my desired parameters, I also come across the SN65MLVD203B. What concerns do you have about using this component for AUX signals?

Regards,

Torsten

Hi Torsten:

  First, fast AUX is not required for DP  anymore.

  AUX signal is bi -directional, we don't have solution for 2-1 or 1-2 for AUX signal  by transceivers like SN65MLVD203B .

   You can just use AUXP  as AUX communication.

Hello Brian,
Your answers are only of limited help to me. I'll ask elsewhere. Thank you very much.

Sorry for limited help. I talked to DP apps in TI. They got same question from customer  before and I was told TI don't have  good solution for such application.
