Hi

I'm designing a DFP for which I'm using the HD3SS3220.

Can you send schematics of eval board?

The one in the HD3SS3220 UFP Dongle Evaluation Module User's Guide is not very clear.

For DFP use, do I connect the SS_TX from the type-C connector to the Tx lines and SS_RX to Rx lines or vice versa?
