PCIe CLKREQ functionality

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. Is this in the tech ref manual?

Hi, nothing special about it.You can get more info in TRM in DLC.
