PCI
The PCI interface on the MPC5200B is designed to PCI Version 2.2 and supports 33-MHz and 66-MHz
PCI operations. See the PCI Local Bus Specification [4]; the component section specifies the electrical and
timing parameters for PCI components with the intent that components connect directly together whether
on the planar or an expansion board, without any external buffers or other “glue logic.” Parameters apply
at the package pins, not at expansion board edge connectors.
The MPC5200B is always the source of the PCI CLK. The clock waveform must be delivered to each
33-MHz or 66-MHz PCI component in the system. Figure 9 shows the clock waveform and required
measurement points for 3.3 V signaling environments. Table 22 summarizes the clock specifications.
