13 PCI

This section describes the DC and AC electrical specifications for the PCI bus of the MPC8349EA.

13.1

PCI DC Electrical Characteristics

Table 44 provides the DC electrical characteristics for the PCI interface of the MPC8349EA.

13.2

PCI AC Electrical Specifications

This section describes the general AC timing parameters of the PCI bus of the MPC8349EA. Note that the

PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the device is

configured as a host or agent device. Table 45 provides the PCI AC timing specifications at 66 MHz.
