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

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.

Key Features

  • 3.3 V operation.
  • Four differential CPU clock pairs.
  • Ten PCI clocks at 3.3 V.
  • Four 66 MHz clocks at 3.3 V.
  • Two 48 MHz clocks at 3.3 V.
  • Two 14.318 MHz reference clocks.
  • 100 or 133 MHz operation.
  • Power management control pins.
  • CPU clock skew less than 200 ps cycle-to-cycle.
  • CPU clock skew less than 150 ps pin-to-pin.
  • 1.5 ns to 3.5 ns delay on PCI pins.
  • Spread Spectrum capability.
