This section describes the PLL configuration of the device. Note that the platform clock is identical to the
CCB clock.

Clock Ranges
Table 55 provides the clocking specifications for the processor core and Table 56 provides 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 15.2, “Platform/System PLL Ratio,” and Section 15.3, “e500 Core PLL Ratio,” for ratio settings.
2.)The minimum e500 core frequency is based on the minimum platform frequency of 200 MHz.
3.)The 1.0 GHz core frequency is based on a 1.3 V VDD supply voltage.

frequencies. Refer to Section 15.2, “Platform/System PLL Ratio,” and Section 15.3, “e500 Core PLL Ratio,” for ratio settings.
2. The memory bus speed is half of the DDR data rate, hence, half of the platform clock frequency.
3.)The 1.0 GHz core frequency is based on a 1.3 V VDD supply voltage.
