W83194BR-S 200MHZ 2-DIMM CLOCK FOR SOLANO CHIPSET 1.0 GENERAL DESCRIPTION The W83194BR-S is a Clock Synthesizer for Intel 815 Solano chipset. W83194BR-S provides all clocks required for high-speed RISC or CISC microprocessor and also provides 64 different frequencies of CPU, SDRAM, PCI, 3V66, IOAPIC clocks frequency setting. All clocks are externally selectable with smooth transitions. The W83194BR-S provides I2C serial bus interface to program the registers to enable or disable each clock outputs and provides 0.25% and 0.5% center type spread spectrum to reduce EMI. The W83194BR-S provides stepless frequency programming by controlling the VCO freq. and the clock output divisor ratio. Also the skew of CPU, SDRAM and 3V66 clock outputs are programmable.
