NOTE:
1. 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. Until phase lock is obtained, the specifications for propagation
delay, skew, and jitter parameters given in the switching characteristics table are not applicable.
SWITCHING CHARACTERISTICS
Over recommended ranges of supply voltage and operating free-air temperature, CL = 30 pF

NOTES:
1. These parameters are not production tested.
2. This is considered as static phase offset.
3. Phase error does not include jitter. (tphase error = static tphase error – jitter (cycle-cycle)).
4. The tSK(0) specification is only valid for outputs with equal loading.
