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.
Either synchronous (CPU/2) or asynchronous (32 MHz)
PCI bus operation can be selected by latching data on
BSEL input.
