Data in Typical column was characterized at 5.0 V, 25 °C or is typical recommended value.
The resulting bus clock frequency should not exceed the maximum specified bus clock frequency of the device.
This parameter is characterized and not tested on each device.
This specification applies to any time the FLL reference source or reference divider is changed, trim value changed or changing
from FLL disabled (FBELP, FBILP) to FLL enabled (FEI, FEE, FBE, FBI). If a crystal/resonator is being used as the reference,
this specification assumes it is already running.
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
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 V
for a given interval.
