    Hi Kevin,

    Can you elaborate on the application for this design? It looks similar to our HD3SS3220 UFP EVM, but are you operating between a USB-C port and type-A port, or are you installing this part on the sink device? (Only type-C port exposed)

    Can you show how the MUX connects to your type-C connector? I don't see this in the schematic.

    You seem to have 0.33uF capacitors on your TX lines. You need to change these to 0.22uF to fit the USB spec for TX capacitance:

    Best,
