General Parameters
5.2.1 Clock AC Specifications
Table 8 provides the clock AC timing specifications for the MPC7448 part numbers discussed here.
NOTE
The core frequency information in this table applies when the device
operates at the nominal core voltage indicated in Table 4. For core
frequency specifications at derated core voltage conditions, see Section 5.3,
Table 8. Clock AC Timing Specifications
At recommended operating conditions. See Table 4.

Notes:
1. Caution: The SYSCLK frequency and PLL_CFG[0:5] settings must be chosen such that the resulting SYSCLK (bus) frequency,
processor core frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating frequencies.
Refer to the PLL_CFG[0:5] signal description in Section 9.1.1, “PLL Configuration,” in the hardware specifications for valid
PLL_CFG[0:5] settings.
8. This reflects the maximum and minimum core frequencies when the dynamic frequency switching feature (DFS) is disabled.
fcore_DFS provides the maximum and minimum core frequencies in a DFS mode.
9. Caution: These values specify the maximum processor core and VCO frequencies when the device is operated at the nominal
core voltage. If operating the device at the derated core voltage, the processor core and VCO frequencies must be reduced. See
Section 5.3, “Voltage and Frequency Derating,” for more information.
10.This specification supports the Dynamic Frequency Switching (DFS) feature and is applicable only when one of the DFS modes
(divide-by-2 or divide-by-4) is enabled. When DFS is disabled, the core frequency must conform to the maximum and minimum
frequencies stated for fcore.
