I am building a custom carrier board which uses USB type C connectors for USB 3.0 and a TI HD3SS3220 mux for handling the type C connector orientation. However, the pinout of the USB type C connector means that in one orientation the TX and RX differential pair polarities need to be flipped to meet USB 3.0 routing spec (i.e., connector SS_TX_P must connect to TX2i SS_TX_N and connector SS_TX_N to TX2i SS_TX_P). USB 3.0 spec calls for PHYs to be able to handle flipped polarities on the SS differential signals, but there is no mention of whether or not the TX2i can handle this online or in its OEM design guide. I assume that it can, but I want to make sure.
I basically have the same question as this thread: USB 3.0 SUPER SPEED POLARITY SWAP IN DIFFERENTIAL PAIR SUPPORT FOR TX2
The thread linked above was answered with a link to another thread that does not answer the question though. I am using a mux for USB C, but it does not solve the problem of having to flip the differential pairs.
