SN65LVPE501: Polarity Inversion

Brian Hammerbacher

Part Number: SN65LVPE501

Hello,

I am designing a board using the Cyclone 10 GX which has an errata where it doesn't do proper automatic RX polarity inversion.  I am trying to find a simple way to fix this issue and was wondering if this redriver would do that for me.  If not, would there be another chip that may work for me.  As small and lowest power solution as possible.  

Thanks,

Brian

    Hello -

    A redriver is not protocol aware device, so it cannot perform automatic polarity inversion.  It allows the user to manually invert the polarity to accommodate easier routing. However, the PCIe root compex, an endpoint, or a retimer would be the devices that perform the automatic polarity inversion.
