A brief overview of the PCI Express common clock (CC) jitter model, and the transfer functions as they relate to the timing PLLs. This model applies to PCI Express (PCIe) Gen 2, Gen 3, Gen 4 and Gen 5. The equations would be slightly different for other PCIe architectures, such as SRIS, SRnS, or data clocked.
