ICS9169C-232 - Frequency Generator for Pentium Based Systems

Description

The ICS9169C-232 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.

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

Features

  • Strong output drive. 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.

www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS9169C-232 Frequency Generator for Pentium™ Based Systems General Description The ICS9169C-232 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. 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. A raised frequency setting of 68.5 MHz is available for Turbo-mode of the 66.8 MHz CPU. The ICS9169C-232 contains 8 CPU clocks, 6 PCI clocks, 1 REF at 48MHz and 1 at 24MHz.
