Clocking

Clock Ranges
Table 64 provides the clocking specifications for the processor cores and Table 65 provides the clocking
specifications for the memory bus. Table 66 provides the clocking for the Platform/MPX bus and Table 67
provides the clocking for the Local bus.

Notes:
1. Caution: The MPX clock to SYSCLK ratio and e600 core to MPX clock ratio settings must be chosen such that the resulting
SYSCLK frequency, e600 (core) frequency, and MPX clock frequency do not exceed their respective maximum or minimum
operating frequencies. Refer to Section 18.2, “MPX to SYSCLK PLL Ratio,” and Section 18.3, “e600 to MPX clock PLL Ratio,”
for ratio settings.
2. The minimum e600 core frequency is based on the minimum platform clock frequency of 400 MHz.

Notes:
1. Caution: The MPX clock to SYSCLK ratio and e600 core to MPX clock ratio settings must be
chosen such that the resulting SYSCLK frequency, e600 (core) frequency, and MPX clock
frequency do not exceed their respective maximum or minimum operating frequencies. Refer to
ratio settings.
2. The memory bus clock speed is half the DDR/DDR2 data rate, hence, half the MPX clock
frequency.
