Stabilization
time (bypass mode)
The time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its reference signal. For phase lock to be obtained,
a fixed-frequency, fixed-phase reference signal must be present at CLK and VDD must be applied. Until phase lock is obtained, the specifications
for propagation delay, skew, and jitter parameters given in the switching characteristics table are not applicable. This parameter does not apply
for input modulation under SSC application.
A recovery time is required when the device goes from power-down mode into bypass mode (AVDD at GND).
