PCK2020 Datasheet Ck00 100/133mhz Spread Spectrum Differential System Clock Generator

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS PCK2020 CK00 (100/133MHz) spread spectrum differential system clock generator Product specification Supersedes data of 2000 Jul 25 2000 Nov 13 Philips Semiconductors Philips Semiconductors Product.

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.
