Electrical and Thermal Characteristics
Table 7 provides the operating frequency information for the MPC8245 at recommended operating
4.5.1
Clock AC Specifications
Table 8 provides the clock AC timing specifications at recommended operating conditions, as defined in
Section 4.5.2, “Input AC Timing Specifications.” These specifications are for the default driver strengths
indicated in Table 4.

Notes:
1. For details, refer to the hardware specifications addendum MPC8245ECSO2AD.
2. Caution: The PCI_SYNC_IN frequency and PLL_CFG[0:4] settings must be chosen such that the resulting peripheral
logic/memory bus frequency and CPU (core) frequencies do not exceed their respective maximum or minimum operating
frequencies. Refer to the PLL_CFG[0:4] signal description in Section 6, “PLL Configurations,” for valid PLL_CFG[0:4] settings
and PCI_SYNC_IN frequencies.
3. See Table 17 and Table 18 for details on VCO limitations for memory and CPU VCO frequencies of various PLL
configurations.
4. No available PLL_CFG[0:4] settings support 133-MHz memory interface operation at 300- and 350-MHz CPU operation,
since the multipliers do not allow a 300:133 and 350:133 ratio relation. However, running these parts at slower processor
speeds may produce ratios that run above 100 MHz. See Table 17 for the PLL settings.
