TMDS181: Use of HPD in Retimer mode

Part Number:TMDS181

Hi

First of all, the following image is ideal. However, we couldn't find proper switch solution.

So, we are considering following, using TMDS181 and TS3DV642.

Additionally, we want to make all device go to low power state if there is no valid signal.

So, the following is our idea.

I think some logic ICs to handle other control signal for channel selection would be required but I did not display them for simplifying image.

Could you check if the our configuration is reasonable, and give us your view?

BestRegards
