Dynamic Characteristics
Clock AC Specifications
Table 11 provides the clock AC timing specifications as defined in Figure 5.
Notes:
1. Rise and fall times for the SYSCLK input are measured from 0.4V to 2.4V.
2. Cycle-to-cycle jitter is guaranteed by design.
3. Timing is guaranteed by design and characterization, and is not tested.
4. PLL relock time is the maximum amount of time required for PLL lock after a stable V

and SYSCLK are
reached during the power-on reset sequence. This specification also applies when the PLL has been disabled and subse-
quently 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 (100 μs) during the power-on reset sequence.

Caution
: The SYSCLK frequency and PLL_CFG[0-3] settings must be chosen such that the resulting SYSCLK (bus) fre-
quency, CPU (core) frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating
frequencies. Refer to the PLL_CFG[0-3] signal description for valid PLL_CFG[0-3] settings.
