AC Characteristics
This section describes AC timing characteristics for each peripheral system.
1 Data in the Typical column was characterized at 5.0 V, 25
C, or the typical recommended value.
2 This parameter is characterized and not tested on each device.
3 This specification applies to any time the FLL reference source or reference divider is changed, trim value changed,
DMX32 bit changed, DRS bit changed, or changing from FLL disabled (FBELP, FBILP) to FLL enabled (FEI, FEE, FBE,
and FBI). If a crystal/resonator is being used as the reference, this specification assumes it is already running.
4 Jitter is the average deviation from the programmed frequency measured over the specified interval at the maximum
fBus. Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal.
Noise injected into the FLL circuitry via VDD and VSS and a variation in the crystal oscillator frequency increases the
CJitter percentage for a given interval.
