The W83193R-01 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumPro , AMD or Cyrix. Eight different frequency of CPU and PCI clocks are externally selectable with smooth transitions. The W83193R-02/-04 also provides I2C serial bus interface to program the registers to enable or disable .

• Supports Pentium™, Pentium™ Pro, Pentium™ II, AMD and Cyrix CPUs with I2C. 4 CPU clocks. 12 SDRAM clocks for 3 DIMs. 7 PCI synchronous clocks. One IOAPIC clock for multiprocessor support. Optional single or mixed supply: (Vdd = Vddq3 = Vddq2 = 3.3V) or (Vdd = Vddq3 = 3.3V, Vddq2 = 2.5V) < 250ps skew among CPU and SDRAM clocks. < 250ps skew among PCI clocks. Smooth frequency switch with selections from 50 MHz to 83.3 MHz CPU. I2C 2-Wire serial interface. 0.6% or 1.5% center type spread spectrum function to reduce EMI. Programmable registers to enable/stop each ou.
