    Hi Thomas,

    The SN75LVPE801 is not fully PCIe compliant.  The input terminations are not 100% detectable using the RXDET process defined in PCIe. 

    The PCIe L1.2 state turns most of the PCIe functionality off to save power.  No testing is planned to identify if the SN75LVPE801 is compatible with PCIe L1.2 power saving features and requirements.

    Regards,

    Lee
