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.

This video compares PCIe Gen3–7 common clock jitter filters with a typical 12kHz to 20MHz plot to highlight the differences in filtering approaches.
A brief overview of how data rates have changed from PCI Express (PCIe) Generation 1, Gen 2, Gen 3, Gen 4 and Gen 5.
