SpletThe PCIe standard specifies a 100 MHz clock (Refclk) with at least ±300 ppm frequency stability for Gen 1, 2, 3 and 4, and at least ±100 ppm frequency stability for Gen 5, at both the transmitting and receiving devices. It also specifies support for three different clocking architectures: Common Clock, Data Clock, Separate Reference Clocks. SpletPCIe總線也有其弱點，其中最突出的問題是傳送延時。. PCIe鏈路使用串行方式進行數據傳送，然而在芯片內部，數據總線仍然是並行的，因此PCIe鏈路接口需要進行串並轉換，這 …
