PCK2020 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.
