Notes: 1. Parameters are guaranteed by design and characterization. Not 100% tested in production.
2. Cycle to cycle jitter and output frequency are included spread spectrum modulation.
3. Stabilization time is the time required for the integrated circuit to obtain phase lock of its input
signal after power up.
