DESCRIPTION

The PCK2023 is a clock synthesizer/driver for a Pentium IV and

other similar processors.

The PCK2023 has three differential pair CPU current source

outputs. There are ten PCI clock outputs running at 33 MHz and two

48 MHz clocks. There are six 3V66 outputs. Finally, there is one

3.3 V reference clock 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.
