Data in Typical column was characterized at 3.0 V, 25 °C or is typical recommended value.
See crystal or resonator manufacturer’s recommendation.
This parameter is characterized and not tested on each device.
Proper PC board layout procedures must be followed to achieve specifications.
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.
