Notes:
1. Absolute maximum ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be
operated beyond these limits.
2. tSU is time to stable output frequency after VDD is applied. tSU and tEN (after EN is asserted) are identical values.
3. See typical cycle to cycle jitter graph for frequency dependence.
