PLL Clock Driver Timing Requirements and Switching Characteristics
Note: 1
Notes: 1. The timing and switching specifications for the PLL listed above are critical for proper
2. The PLL must be able to handle spread spectrum induced skew.
3. Operating clock frequency indicates a range over which the PLL must be able to lock, but
4. Stabilization time is the time required for the integrated PLL circuit to obtain phase lock of
5. Static Phase Offset does not include Jitter.
6. Period Jitter and Half-Period Jitter specifications are separate specifications that must be
