ICS9248-81 - Frequency Generator & Integrated Buffers

The ICS9248-81 is the single chip clock solution for Desktop/ Notebook designs using the SIS style chipset.

It provides all necessary clock signals for such a system.

Spread spectrum may be enabled through I2C programming.

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

This simplifies
