Clock For SiS Chipsets

W83194BG-803 is a Clock Synthesizer for SIS K8 chipset, which provides all Clocks required for high-speed Microprocessor and provides step-less frequency programming and 32 different frequencies of CPU, PCI and AGP Clocks setting, support two ZCLK Clock outputs; all Clocks are externally selectable with smooth transitions.
W83194BG-803 supports I2C serial bus Interface to program the Registers to enable or disable each Clock outputs and provides -0.5% and +/-0.25% center type spread spectrum or programmable S.S.T. scale to reduce EMI It also has watchdog Timer and reset output pin to support auto-reset when systems hanging caused by improper frequency setting.
W83194BG-803 accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply.
