19.1 19.1 ASYNCHRONOUS CLOCK SUPPORT
PERICOM SEMICONDUCTOR - Confidential
PI7C9X130 supports PCI Express Asynchronous Clock Domain only in a x1 PCIe Link interface. To
operate in a x4 PCIe Link, REFCLK pin of PI7C9X130 requires a synchronous clock source from the same
clock domain of PCIe Root Complex or PCIe End Point that PI7C9X130 is connected to. The
requirement of synchronous clock source applies to both Forward and Reverse Mode Operations.
