Processor Bus AC Specifications
Table 9 provides the processor bus AC timing specifications for the MPC7457 as defined in Figure 4 and
Figure 5. Timing specifications for the L3 bus are provided in Section 5.2.3, “L3 Clock AC

Notes:
1. Caution: The SYSCLK frequency and PLL_CFG[0:4] settings must be chosen such that the resulting SYSCLK (bus)
frequency, CPU (core) frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating
frequencies. Refer to the PLL_CFG[0:4] signal description in Section 1.9.1, “PLL Configuration,” for valid PLL_CFG[0:4]
settings.
2. Assumes lightly-loaded, single-processor system; see Section 5.2.1, “Clock AC Specifications” for more information.
3. Rise and fall times for the SYSCLK input measured from 0.4 to 1.4 V.
4. Timing is guaranteed by design and characterization.
5. Guaranteed by design.
6. The SYSCLK driver’s closed loop jitter bandwidth should be less than 1.5 MHz at –3 dB.
7. Relock timing is guaranteed by design and characterization. PLL-relock time is the maximum amount of time required for PLL
lock after a stable VDD and SYSCLK are reached during the power-on reset sequence. This specification also applies when
the PLL has been disabled and subsequently re-enabled during sleep mode. Also note that HRESET must be held asserted
for a minimum of 255 bus clocks after the PLL-relock time during the power-on reset sequence.
