TS3DV642: application for DP++1.2 and eDP

Sam Ting

Part Number: TS3DV642

Hi team,

My customer had a design with TS3DV642 to switch between LVDS and eDP and the operation is fine.

Now they want to extend the application to switch between DP++1.2 and eDP as shown below. Could you please comment if TS3DV642 is suitable for the application? Thanks!

New MUX design for DP++1.2 and eDP:

DP++1.2 / eDP inputs:

You would need to AC couple the DP++ main link output. For the EDID_DATA and EDID_CLK, is this the DDC bus or the AUX bus that supports I2C-over-AUX?

Thanks

Hi David,

Thanks for your feedback.

In current design, the EDID_DATA and EDID_CLK will be the AUX bus that supports I2C-over-AUX.

Is there any potential issue for this application?

Thanks

Sincerely,

Edward

Please make sure the AUX bus is AC-coupled and have the 100k pullup/pulldown on it. Do you want me to review the schematic?

Thanks
