Time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its reference signal. In order for phase lock to

be obtained, a fixed-frequency, fixed-phase reference signal must be present at CLKIN. Until phase lock is obtained, the specifications

for propagation delay and skew parameters given in the switching characteristicstable are not applicable.
