Overview

The ICS9169C-231 is a low-cost frequency generator designed specifically for Pentium and Pentium-Pro based chip set systems. The integrated buffer minimizes skew and provides all the clocks required.

  • Eight selectable CPU clocks operate up to 83.3 MHz Frequency selections include Turbo-mode speed of 68.5 MHz 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 to BUS clocks skew 1-4 ns (CPU early) 48 MHz clock for USB support & 24 MHz clock for FD. Logic inputs latched at Power-On for frequency selection saving pins as Input/Output Integrated buffer outputs drive up to 30pF loads 3.0V - 3.7V supply range, CPU (1:8) outputs 2.5V (2.375 - 2.6V) VDD option 28-pin SOIC or SSOP package
