Hi NV team，

《Jetson Orin NX Series and Jetson Orin Nano Series Product Design Guide_DG-10931-001_v1.2》 tells 85 ohm differential impedance for PCIE3.0/4.0， so that means PCIE_REFCLK_P/N is also 85ohm differential impendance ？or could it be 100ohm differntial impedance for PCIE_REFCLK_P/N and 85ohm differential impedance for PCIE_TX/RX_P/N？

It is 85ohm with +/-15% tolerance.
