For more information, see Section 13.2, “SerDes Reference Clocks.”
14.2
AC Requirements for PCI Express SerDes Clocks
Table 48 lists AC requirements.
14.3
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.
14.4
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 please use the PCI
EXPRESS Base Specification. REV. 1.0a document.
14.4.1
Differential Transmitter (TX) Output
Table 49 defines the specifications for the differential output at all transmitters (TXs). The parameters are
specified at the component pins.
