Freescale Semiconductor

PCI/PCI-X

12 PCI/PCI-X

This section describes the DC and AC electrical specifications for the PCI/PCI-X bus of the MPC8560.

12.1 PCI/PCI-X DC Electrical Characteristics

Table 41 provides the DC electrical characteristics for the PCI/PCI-X interface of the MPC8560.

12.2 PCI/PCI-X AC Electrical Specifications

This section describes the general AC timing parameters of the PCI/PCI-X bus of the MPC8560. Note that the

SYSCLK signal is used as the PCI input clock. Table 42 provides the PCI AC timing specifications at 66 MHz.
