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 @ 2.7V

? 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:

VIA KT266 style chipset
