Hi Sir,

My customer would like to kno if there is any timing requirement between GRST and PCIe clock?

Which on should apply first? Or there is no requirement between GRST and PCIe clock?

Thanks,

Patrick

Hello,

There is no timing requirement between GRST# and PCIE_REFCLK, however, the power-up sequence described in Datasheet Section 9.1.1 must be met.
