General Description
The ICS94229 is a main clock synthesizer chip for AMD-K7 based systems with VIA KT266 style chipset. This provides all clocks required for such a system.

Features:
• Programmable output frequency.
• Programmable output rise/fall time.
• Programmable slew and skew control for CPUCLK, PCICLK, AGP, REF, 48MHz and 24_48MHz.
• 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:
• 1 - Differential pair open drain CPU clocks @ 2.5V
• 1 - Differential pair push-pull CPU clocks @ 2.5V
• 11 - PCI including 1 free running and 1 early @ 3.3V
• 1 - 48MHz, @ 3.3V fixed
• 1 - 24/48MHz @ 3.3V
• 3 - REF @ 3.3V, 14.318MHz.

Recommended Application:
