1. The timing and switching specifications for the PLL listed above are critical for proper operation of the DDR SDRAM
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 in which it is not required to
4. Stabilization time is the time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its ref-
5. Static Phase Offset does not include Jitter.
6. Period Jitter and Half-Period Jitter specifications are separate specifications that must be met independently of each
7. The Output Slew Rate is determined from the IBIS model:
Registered DIMMs. These are meant to be a subset of the parameters for the specific device used on the module.
Detailed information for this PLL is available in JEDEC Standard JESD82.
