Data in Typical column was characterized at 3.0 V, 25°C or is typical recommended value.
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
percentage for a given interval.
