Electrical Characteristics

When ICS is configured for FEE or FBE mode, input clock source must be divisible using RDIV to within the range of 31.25 kHz
to 39.0625 kHz.
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, DMX32 bit
is changed, DRS bit is 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
given interval.
