20 Clocking
This section describes the PLL configuration of the MPC8548E. Note that the platform clock is identical
to the core complex bus (CCB) clock.
20.1
Clock Ranges
Table 75 through Table 77 provide the clocking specifications for the processor cores and Table 78,
through Table 80 provide the clocking specifications for the memory bus.

Notes:
1. Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK
frequency, e500 (core) frequency, and CCB frequency do not exceed their respective maximum or minimum operating
frequencies. Refer to Section 20.2, “CCB/SYSCLK PLL Ratio,and Section 20.3, “e500 Core PLL Ratio,for ratio settings.
2.)The minimum e500 core frequency is based on the minimum platform frequency of 333 MHz.
