ICS9169C-26 - Frequency Generator and Integrated Buffers - ICST 数据手册 ( 数据表 )

General Description
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.
