Platform to Sysclk Frequency Options
Table 80 shows the expected frequency values for the platform frequency when using the specified CCB
clock to SYSCLK ratio.

Minimum Platform Frequency Requirements for High-Speed
Interfaces
Section 4.4.3.6 “I/O Port Selection” of the MPC8572E PowerQUICC III Integrated Host Processor
Family Reference Manual, describes various high-speed interface configuration options. Note that the
CCB clock frequency must be considered for proper operation of such interfaces as described below.
For proper PCI Express operation, the CCB clock frequency must be greater than or equal to:
See Section 21.1.3.2, “Link Width” of the MPC8572E PowerQUICC III Integrated Host Processor
Family Reference Manual, for PCI Express interface width details. Note that the “PCI Express link width”
in the above equation refers to the negotiated link width as the result of PCI Express link training, which
may or may not be the same as the link width POR selection.
For proper serial RapidIO operation, the CCB clock frequency must be greater than:
See Section 20.4, “1x/4x LP-Serial Signal Descriptions” of the MPC8572E PowerQUICC III Integrated
Host Processor Family Reference Manual, for serial RapidIO interface width and frequency details.
