Ensure you're logged in or provide company details for full access. Refer to ISO/IEC 7816-3 for details on voltage and current Is there anything special about the way that CLKREQ works in the PCIe IP? Our current plan is to have the other devices on the board toggle the CLKREQ# pin low and receive a ref clk from the Xavier – at face value this seems pretty typical/normal for PCIe but I am coming into this project rather cold so I don’t want to make any assumptions. The LSF0204 can use in 1. The PCIe External Cable 3.
