Notes:
1. Caution: The SYSCLK frequency and PLL_CFG[03] 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[03] signal description in Section 1.8, System Design Information, for valid
PLL_CFG[03] settings, and to Section 1.9, Ordering Information, for available frequencies
and part numbers.
2. Rise and fall times for the SYSCLK input are measured from 0.4 V to 1.8 V.
3. Timing is guaranteed by design and characterization, and is not tested.
4. Cycle-to-cycle jitter, and is guaranteed by design.
5. PLL-relock time is the maximum time required for PLL lock after a stable Vdd, OVdd, AVdd,
and SYSCLK are reached during the power-on reset sequence. Also note that HRESET
must be held asserted for a minimum of 255 bus clocks after the PLL-relock time (100
ms)
during the power-on reset sequence.
6. 604e processors are tested at the maximum SYSCLK frequencies shown in the AC timing
specications. It is possible to attain higher SYSCLK frequencies through proper system
design.
