GENERAL DESCRIPTION
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.

PRODUCT FEATURES
•  Supports PentiumÔ, PentiumÔ Pro, PentiumÔ 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 output and select modes. (mode as Tri-state, or Normal )
•  MODE pin for power Management.
•  48 MHz for USB.
•  24 MHz for super I/O.
•  48-pin SSOP package.
