Pentium is a trademark on Intel Corporation.
The ICS9169C-26 is a low-cost frequency generator
designe 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.
Either synchronous (CPU/2) or asynchronous (32 MHz)
PCI bus operation can be selected.
