General Description
The ICS94211 is a single chip clock solution for desktop designs using the BX/Apollo Pro133/ALI 1631 style chipset. It provides all necessary clock signals for such a system.
FEATUREs:
• Programmable ouput frequency.
• Programmable ouput rise/fall time.
• Programmable PCICLK, PCICLK_F, SDRAM skew.
• Real time system reset output
• 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
