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,
4. Stabilization time is the time required for the integrated PLL circuit to obtain phase
5. Static Phase Offset does not include Jitter.
6. Period Jitter and Half-Period Jitter specifications are separate specifications that must
7. The output slew rate is determined from the IBIS model:
operation of DDR SDRAM modules. These are meant to be a subset of the parameters
for the specific device used on the module. Detailed information for this PLL is avail-
able in JEDEC Standard JESD82.
