Notes to Table 1–23:

(1) Dedicated refclk pins were used to drive the input reference clocks.

(2) The jitter numbers specified are valid for the stated conditions only.

(3) The jitter numbers for PIPE are compliant to the PCIe Base Specification 2.0.

(4) The jitter numbers for GIGE are compliant to the IEEE802.3-2002 Specification.
