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 …
