HD3SS3220: HD3SS3220 at UFP mode USB TX+/- / RX+/- swap

Part Number: HD3SS3220


Now we use HD3SS3220 at UFP mode.

When we follow P/N connection as below, what should be consider?

Does it have any compatibility issue?

  • TX1p/TX1n and RX1p/RX1n are P/N swapped connection.

  • TX2p/TX2n and RX2p/RX2n are not P/N swapped connection.

  • TXp/TXn and RXp/RXn are not P/N swapped connection.

Please provide reference schematic and layout board file for checking.
