Overview

  • Eight independent clock outputs handle all clocking requirements for personal computer motherboards
  • CPU clock frequency range: 10 MHz to 100 MHz with user-defined duty cycle
  • Four user-configurable outputs
  • Skew-free CPU clock, CPU clock รท2, and buffered CPU clock options on configurable outputs
  • Ideally suited for desktop PCs
  • Phase-locked loop oscillator input derived from single 14.31818 MHz crystal
  • Sophisticated internal loop-filter requires no external components
  • Battery input maintains 32.768 kHz clock during power-down
  • Three-state oscillator control disables outputs for test purposes
  • 5V operation
