PCK2020
Datasheet
General description
The PCK2020 is a clock synthesizer/driver for a Pentium III and other similar processors.
The PCK2020 has four differential pair CPU current source outputs, two Mref clock outputs running at 1/2 the CPU clock frequency depending on the state of SEL133/100 pin and four 3V66 clocks running at 66 MHz. There are ten PCI clock outputs running at 33 MHz and two 48 MHz clocks. Finally, there are two 3.3 V reference clocks at 14.318 MHz. All clock outputs meet Intel?s drive strength, rise/fall times, jitter, accuracy, and skew requirements.
The part possesses a dedicated power-down input pin for power management control. This input is synchronized on-chip and ensures glitch-free output transitions.
