We have a question regarding PCIe differential pair polarity inversion.
Can the PCIe reference clock pair (REFCLK+/-) also support P/N swapping, similar to the PCIe TX/RX data lanes?
According to the Design Guide, P/N swapping is explicitly specified only for the interfaces listed in Tables 7-1 and 7-2. We could not find any statement regarding support for P/N swapping on the PCIe reference clock pair.
Could you please confirm whether P/N swapping is supported for the PCIe reference clock pair?
