1.4.2.1 Clock AC Specications
Table 7 provides the clock AC timing specications as dened in
Figure 1. After fabrication, parts are sorted
for conformance to the AC specications for that frequency. Parts are sold by maximum processor core

Notes:
1. Caution: The SYSCLK frequency and PLL_CFG[0–3] 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[0–3] signal description
2. Rise and fall times for the SYSCLK input are measured from 0.4 V to 2.4 V.
3. Timing is guaranteed by design and characterization, and is not tested.
4. Cycle-to-cycle jitter, and is guaranteed by design. The total input jitter (short term and long term
5. Relock timing is guaranteed by design and characterization, and is not tested. 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. This specication 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 (100
ms) during the power-on reset sequence.
6. Operation below 150 MHz is supported only by PLL_CFG[0–3] = 0b0101. Refer to
Section 1.8.1, “PLL
