TIMING REQUIREMENTS
NOTES:
1. The PLL will track a spread spectrum clock input.
2. Operating clock frequency is the range over which the PLL will lock, but may not meet all timing specifications. To be used only for low speed system debug.
3. Application clock frequency is the range over which timing specifications apply.
4. Stabilization time is the time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its reference signal after power up. During normal operation, the
5. Will lock to input frequency as low as 30MHz at room temperature and nominal or higher supply voltage (1.8V - 1.9V).

stabilization time is also the time required for the PLL circuit to obtain phase lock of its feedback signal to its reference signal when CLK and CLK go to a logic LOW state, enters
the power-down mode, and later return to active operation. CLK and CLK may be left floating after they have been driven LOW for one complete clock cycle.
