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.

Physical Layer Specifications
The 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 refer to PCI Express Base
Specification. Rev. 1.0a.
16.4.1
Differential Transmitter (TX) Output
Table 52 defines the specifications for the differential output at all transmitters (TXs). The parameters are
specified at the component pins.

Each UI is 400 ps ± 300 ppm. UI does not account
for spread spectrum clock dictated variations.

Ratio of the VTX-DIFFp-p of the second and
following bits after a transition divided by the
VTX-DIFFp-p of the first bit after a transition.

UI
The maximum transmitter jitter can be derived as
TTX-MAX-JITTER = 1 – TTX-EYE = 0.3 UI.

UI
Jitter is defined as the measurement variation of
the crossing points (VTX-DIFFp-p = 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.
See Notes 2 and 3.
