General Description

The ICS94209 is a single chip clock solution for desktop designs using 630S chipsets. It provides all necessary clock signals for such a system.

Features:

• Programmable ouput frequency.

• Programmable ouput rise/fall time.

• Programmable SDRAM and CPU skew.

• Spread spectrum for EMI control typically by 7dB to 8dB, with programmable spread percentage.

• Watchdog timer technology to reset system if over-clocking causes malfunction.

• Uses external 14.318MHz crystal.

• FS pins for frequency select

Output Features:

• 3 - CPU @ 2.5V

• 13 - SDRAM @ 3.3V

• 6- PCI @3.3V,

• 2 - AGP @ 3.3V

• 1- 48MHz, @3.3V fixed.

• 1- 24/48MHz, @3.3V selectable by I2C (Default is 24MHz)

• 2- REF @3.3V, 14.318MHz.
