W83194AR-96 200MHZ CLOCK FOR WHITNEY CHIPSET 1.0 GENERAL DESCRIPTION The W83194AR-96 is a Clock Synthesizer for Intel Whitney chipset. W83194AR-96 provides all clocks required for high-speed RISC or CISC microprocessor and also provides 32 different frequencies of CPU, SDRAM, PCI, 3V66, IOAPIC clocks frequency setting. All clocks are externally selectable with smooth transitions. The W83194AR-96 provides I C serial bus interface to program the registers to enable or disable each clock outputs and provides 0.25% center and 0-0.5% down type spread spectrum to reduce EMI. The W83194AR-96 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.
