Why the capacitors between SSTX on the chip and SSRX on the connector? #2

As the title asks, why did you add 0.1uF capacitors between SSTX on the chip and SSRX on the connector? Also, why did you swap SSTX+ and SSTX-? Was this just to make the routing easier? Does it have any impact on maximum data rate?

Hi @taktoa , I was making changes strictly with accordance to with the Hardware Design Guidelines , section 12.1 Capacitors are a must for this chip. You can swap + and - in USB3 differential pairs if it makes your routing easier.
