2 Based on PCIe Base Specification Rev3.1a. These filters are different than Common Clock filters. See http://www.pcisig.com for latest
specifications. There is a proposal to reduce the PCIe Gen3 limit to 0.5ps.
3 As of PCIe Base Specification Rev4.0 draft 0.7, SRIS is not currently defined for Gen1 or Gen4.
