clock frequency
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.
Characteristic
Typical values assume V
reference only and are not tested in production.
