ICS9248YF-189-T, AMD - K7™ Clock Generator for Mobile System

The ICS9248-189 is a main clock synthesizer chip for AMD-K7 based note book systems with VIA style chipset.

This provides all clocks required for such a system.

Spread spectrum may be enabled through I2C programming.

Spread spectrum typically reduces system EMI by 8dB to 10dB.

This simplifies EMI qu
