ICD2028 Overview
A modern personal puter 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. These parts synthesize all the required frequencies in a single monolithic device, thus lowering manufacturing costs and significantly reducing...
ICD2028 Key Features
- Eight independent clock outputs handle all clocking requirements for personal puter 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
- Ideally suited for desktop PCs
- Phase-locked loop oscillator input derived from single 14.31818 MHz crystal
- Sophisticated internal loop-filter requires no external ponents
- Battery input maintains 32.768 kHz clock during power-down
- Three-state oscillator control disables outputs for test purposes
- 5V operation
