    Is this an automotive design application? The block diagram shows a USB3.2 Gen 2 MUX, but the IVI Board Host shows only one pair of TX and RX. 

    For non-automotive, TUSB542 would be a more appropriate solution.

    Thanks

    Hello ,David:

        Nice to meet you, This is Automotive FAE Roy which co-work with Disti FAE Lawrence , customer will design USB PD mux HD3SS3212-Q1 with support USB3.2 Gen2 10Gbps Mux but due to cable is too long (~1m cable length) they will design re-driver , but currently we just only have TUSB501-Q1 Automotive grade redriver only support 5Gbps solution now. 

        do you have 10Gbps automotive grade re-driver solutions? May I know if customer design  HD3SS3212-Q1

    + TUSB501-Q1 application is only support up to 5Gbps speed max ?

    thank you for your help.

    Roy, Lawrence

    The block diagram itself looks ok. You are using the resistor divider network to restore the common mode voltage for HD3SS3212-Q1. With HD3SS3212-Q1 common mode voltage between 0 to 2V, why do you choose resistor divider network that provides ~0.4V, and not 1V common mode voltage?

    Thanks
