DS160PR410: Per lane polarity swaps

Peter vK

Part Number: DS160PR410

PCIe supports per lane polarity swaps. I'm assuming it's OK to arbitrarily invert the input or output polarity of any lane on the DS160PR410, but please let me know if this is not the case.

Thanks!

Sorry should have kept searching - I think this confirms that yes, this is fine - https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1105870/ds160pr410-rxnp-and-rxnn-flip-consult?tisearch=e2e-sitesearch&keymatch=DS160PR410#

Hi Peter,

Yes, polarity swap is allowed. I echo Nasser's recommendation in the previous E2E thread you've linked.

Best,
David
