Clocking Dependencies
The ports on the two ends of a link must transmit data at a rate that is within 600 parts per million (ppm)
of each other at all times. This is specified to allow bit rate clock sources with a ±300 ppm tolerance.
11.4
Physical Layer Specifications
Following is a summary of the specifications for the physical layer of PCI Express on this device. For
further details as well as the specifications of the transport and data link layer, use the PCI Express Base
Specification, Rev. 1.0a.

Differential Transmitter (TX) Output
Table 34 defines the specifications for the differential output at all transmitters (TXs). The parameters are
specified at the component pins.

MAX-JITTER
Jitter is defined as the
measurement variation of
the crossing points
(VPEDPPTX = 0 V) in
relation to a recovered TX
UI. A recovered TX UI is
calculated over 3500
consecutive unit intervals
of sample data. Jitter is
measured using all edges
of the 250 consecutive UI
in the center of the 3500
UI used for calculating the
TX UI.
