MPC8245 Integrated Processor Hardware Specifications
MOTOROLA
Electrical and Thermal Characteristics
1.4.3.1
Clock AC Specifications
Table 8 provides the clock AC timing specifications at recommended operating conditions, as defined in
Section 1.4.3.2, “Input AC Timing Specifications.” These specifications are for the default driver strengths
indicated in Table 4. Figure 6 shows the PCI_SYNC_IN input clock timing diagram with the labeled
number items listed in Table 8.

Notes:
1. See part number specification document MPC8245RZUPNS/D for additional part offering information.
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 1.6, “PLL Configuration,”
for valid PLL_CFG[0:4] settings and PCI_SYNC_IN frequencies.
3. See Table 18 and Table 19 for more details on VCO limitations for memory and CPU VCO frequencies of various
PLL configurations.
4. There are no available PLL_CFG[0:4] settings which support 133 MHz memory interface operation at 300 MHz
CPU and 350 MHz 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 will run above 100 MHz. See Table 18 for
the PLL settings.
