HD3SS3220: swapping TX / RX lines

Part Number: HD3SS3220

Hi all,

I am routing HD3SS3220 according to the datasheet schematic. The SS_TX lines follow from the host to the connector. AC Capacitors are connected TX lines.

Layout example on Figure 22 shows AC capacitors connected to RX lines instead of TX lines.

HD3SS3220 dongle schematics (www.ti.com/.../sllu237a.pdf) uses TX lines of HD3SS3220 between RX lines of USB connectors.

I noticed the note "does not care about the differential pair polarity". I expect it to be valid for positive and negative wire. Does it also mean I can just swap RX and TX internal lines? It would explain it. Or is there anything else I am missing?

Where can I request the PCB design files for the dongle?

Thank you in advance.
