TUSB522P polarity swap

Other Parts Discussed in Thread: TUSB522P

Hi team,

My customer wants to know whether TUSB522P polarity can be swapped on the
RXxP/N and TXxP/N diffential pairs.

I think the polarity can be swapped.

Is this correct? Please let me know.

Best regards,

Hi FN,

The situation is the same for all USB3.0 redrivers:

In USB3 you can swap polarity and the receiver's physical layer will fix it, this is regardless of the redriver you use.

For non-USB3.0 redrivers you can swap polarity at the input and have to swap polarity at output again to go back to the original state.

Regards
