PCK2021 Datasheet (NXP) - CK00 100/133 MHz spread spectrum differential system clock generator

PCK2021, CK00 100/133 MHz spread spectrum differential system clock generator

The PCK2021 is a clock synthesizer/driver for a Pentium III™ and other similar processors.

The PCK2021 has six differential pair CPU current source outputs, two 33 MHz outputs, one 3V66 output, and two 48 MHz clocks which can be disabled on power-up, and one 3.3 V reference clock at 14.318 MHz which
