This section describes the DC and AC electrical specifications for the PCI Express bus of the MPC8640.
14.1
For more information, see
14.2
Table 48
14.3
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.
14.4
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 please use the PCI Express
