This section contains the DC specifications for the physical layer of PCI Express on this device.
2.20.4.5.1
This section discusses the PCI Express AC physical layer transmitter specifications 2.5 GT/s, and 5 GT/s.
This table defines the PCI Express 2.0 (2.5 GT/s) AC specifications for the differential output at all transmitters. The parameters
are specified at the component pins. The AC timing specifications do not include RefClk jitter.

Tx jitter budget collected over any 250 consecutive Tx UIs. Note that the median is not the same as the mean. The jitter median
describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged
time value.

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.
All transmitters must be AC coupled. The AC coupling
is required either within the media or within the
transmitting component itself.
