ICD2028 - PC Motherboard Clock Generator

General Description

A modern personal computer motherboard often requires as many as seven different crystal can oscillators.

The System Logic family of frequency synthesis parts from Cypress/IC Designs replaces the large number of oscillators required to build such multi-function motherboards.

Key Features

  • 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 ÷2, 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-.
