PCK2020 Datasheet (NXP) - CK00 100/133MHz spread spectrum differential system clock generator

PCK2020, CK00 100/133MHz spread spectrum differential system clock generator

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.
