The W83194BR-911 is a Clock Synthesizer for VIA PT880/PM880 chipset. W83194BR-911 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 25MHz clock outputs, all clocks are externally selectable with smooth transitions.
The W83194BR-911 provides 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.
The W83194BR-911 also has watchdog timer and reset output pin to support auto-reset when systems hanging caused by improper frequency setting.
The W83194BR-911 accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply.
