In one of our application using the S32G2 NXP processor (Part Nr: S32G254AABK1VUCT) and PCIe interface is using. A 100MHz (Clock freq configurable) external clock generator is interfaced for PCIE1_CLK_P, PCIE1_CLK_N signals.

Please confirm the clock type - LVDS/ LP-HSCL?

Thank you.

Hello, @gopalakrishna

Thanks for the question.

As far as I know, the external reference clock for PCIe/sgmii is HCSL level on RDB2, you can refer to design files of the RDB2 for details.

May I know if HCSL could also be accepted or have to be LP-HCSL ?

Best Regards
