DS320PR810: Is it possible to swap P and N of each differential pair?

Part Number: DS320PR810

Hi,

DS320PR810 is a Protocol agnostic linear redriver. 

We are looking to swap the invert(N) and non-inverting(P) of differential pair, due to PCB routing.

May I know what is the impact of swapping the differential pin?

    Hi KS,

    Yes you can swap P and I of differential pair for ease of pcb layout. DS320PR810 main target application is PCIe. This protocol is polarity insensitive since it uses NRZ data pattern. So as long as it is used in the same application or NRZ data stream, we can swap P & N.
