The W83194R-17/-17A is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumII, PentiumPro , AMD or Cyrix. Eight different frequency of CPU, AGP and PCI clocks are externally selectable with smooth transitions. The W83194R-17/-17A provides AGP clocks especially for clone chipset. The highest CPU frequency provided by the W83194R-17 is up to 100MHz, but the one of W83194R-17A is up to 133MHz. The W83193R-17/-17A provides I2C serial bus interface to program the registers to enable or disable each clock outputs and choose the 0.5% or 1.5% center type spread spectrum to reduce EMI. The W83194R-17/-17A 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 |
