This parameter is guaranteed by characterization before qualification rather than 100% tested. Applies to external clock
reference only.
Proper PC board layout procedures must be followed to achieve specifications.
This parameter is guaranteed by design rather than 100% tested.
This specification is the PLL lock time only and does not include oscillator start-up time..
C
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 PLL circuitry via PLL V
the Cjitter percentage for a given interval.
