1 Data in Typical column is characterized at 3.0 V, 25
°C or is typical recommended value.
2 The resulting bus clock frequency must not exceed the maximum specified bus clock frequency of the device.
3 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.
4 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Bus.
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 variation in crystal oscillator frequency increase the CJitter percentage
for a given interval.
