General Description
The ICS94225 is a main clock synthesizer chip for AMD-K7 based systems with AMD 750/760 style chipsets. This provides all clocks required for such a system.

FEATUREs:
• Programmable ouput frequency
• Programmable ouput rise/fall time
• Programmable group 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

Output Features:
• 3 differential pair open drain CPU clocks (1.5V external pull-up; up to 150MHz achieviable through I2C)
• 2 - AGPCLK @ 3.3V
• 8 - PCI @3.3V, including 1 free running
• 1 - 48MHz @ 3.3V
• 1 - 24/48MHz @ 3.3V
• 2- REF @3.3V, 14.318MHz.
