The W83194AR-We is a Clock Synthesizer for Intel Whitney chipset. W83194AR-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 W83194AR-We 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 W83194AR-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. CPU CLOCK outputs typically provide better than 1 V /ns slew rate into 20 pF loads as maintaining 50± 5% duty cycle. The fixed frequency outputs as REF, 24MHz, and 48 MHz provide better than 0.5V /ns slew rate.
