ICS9169C-27 - Frequency Generator for Pentium Based Systems

Datasheet Summary

Description

The ICS9169C-27 is a low-cost frequency generator designed specifically for Pentium based chip set systems.

The integrated buffer minimizes skew and provides all the clocks required.

A 14.318 MHz XTAL oscillator provides the reference clock to generate standard Pentium frequencies.

Features

Twelve selectable CPU clocks operate up to 83.3MHz Maximum CPU jitter of ± 200ps Six BUS clocks support sync or async bus operation 250ps skew window for CPU outputs, 500ps skew window for BUS outputs CPU clocks BUS clocks skew 1-4ns (CPU early) Integrated buffer outputs drive up to 30pF loads 3.0V - 3.7V supply range, CPU(1:6) outputs 2.5V(2.3752.62V) VDD option 32-pin SOIC/SOJ package Logic inputs latched at Power-On for frequency selection saving pins as Input/Output 48 MH.

ICS9169C-27 Frequency Generator for Pentium Based Systems General Description The ICS9169C-27 is a low-cost frequency generator designed specifically for Pentium based chip set systems. The integrated buffer minimizes skew and provides all the clocks required. A 14.318 MHz XTAL oscillator provides the reference clock to generate standard Pentium frequencies. The CPU clock makes gradual frequency transitions without violating the PLL timing of internal microprocessor clock multipliers. Twelve CPU clock outputs provide sufficient clocks for the CPU, chip set, memory and up to two DIMM connectors (with four clocks to each DIMM).
