The ICS9169C-23 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 crystal 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 by latching data on BSEL
input.
