ICS9169C-232 Frequency Generator for Pentium Based Systems

ICS9169C-232 Frequency Generator for Pentium Based Systems

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. .
