Notes:
1. Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK
frequency, e500 (core) frequency, and CCB frequency do not exceed their respective maximum or minimum operating
frequencies. Refer to Section 15.2, “Platform/System PLL Ratio,” and Section 15.3, “e500 Core PLL Ratio,” for ratio settings.
2. Rise and fall times for SYSCLK are measured at 0.6 V and 2.7 V.
3. Timing is guaranteed by design and characterization.
4. This represents the total input jitter—short term and long term—and is guaranteed by design.
5. For spread spectrum clocking, guidelines are +/-1% of the input frequency with a maximum of 60 kHz of modulation
regardless of the input frequency.
