TUSB551 polarity swap

F.N

Other Parts Discussed in Thread: TUSB551

Hi team,

My customer wants to know whether TUSB551 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,

In most redriver you can swap polarity at the input and have to swap polarity at output again to go back to the original state.

However, in USB3 you can swap polarity and the receiver's physical layer will fix it.
