W83194BR-C 200MHZ CLOCK FOR CAMINO CHIPSET 1.0 GENERAL DESCRIPTION The W83194BR-C is a Clock Synthesizer for Intel Camino 820 chipset. W83194BR-C provides all clocks required for high-speed RISC or CISC microprocessor and also provides 64 different frequencies of CPU, PCI, 3V66, IOAPIC clocks frequency setting. All clocks are externally selectable with smooth transitions. The W83194BR-C provides I2C serial bus interface to program the registers to enable or disable each clock outputs and provides 0.5% and 0.75% center type spread spectrum to reduce EMI. The W83194BR-C accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply. High drive PCI CLOCK outputs typically provide greater than 1 V /ns slew rate into 30 pF loads.
