Timing Requirements
1.
Part Number
The PLL is able to handle spread spectrum induced skew.
Operating clock frequency indicates a range over which the PLL is able to lock, but in which it is not required to meet the other timing parameters.
(Used for low-speed debug or production testing of DIMM modules).
Application clock frequency indicates a range over which the PLL must meet all timing parameters.
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 stabilization time is also the time required for the integrated PLL circuit to obtain phase lock of its feedback
signal to its reference signal when CK and CK go to a logic low state, enter the power-down mode and later return to active operation. CK and
CK maybe left fl oating after they have been driven low for one complete clock cycle.
CK maybe left fl oating after they have been driven low for one complete clock cycle.
