W83195AR-We 200MHZ 3-DIMM CLOCK FOR WHITNEY CHIPSET 1.0 GENERAL DESCRIPTION The W83195AR-We is a Clock Synthesizer for Intel Solano chipset. W83195AR-We 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 W83195AR-We provides I C 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 W83195AR-We accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply. High drive PCI and SDRAM CLOCK outputs typically provide greater than 1 V /ns slew rate into 30 pF loads.
