17 PCI Express
This section describes the DC and AC electrical specifications for the PCI Express bus of the MPC8548E.
17.1
For more information, see
17.2
Table 55
17.3
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.
17.4
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 see PCI Express Base
Specification. Rev. 1.0a.
