The W83193R-02/-04/-04A is a Main board Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumPro, PentiumII, AMD or Cyrix. Eight different frequency of CPU and PCI clocks are externally selectable with smooth transitions. The W83193R-02/-04/-04A also provides I2C serial bus interface to program .
• Supports Pentium™, Pentium™ Pro, Pentium™ II, AMD and Cyrix CPUs with I C.
2
• 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 = VDDq2b = 3.3V) or (VDD = VDDq3 = 3.3V, VDDq2 = VDD2b = 2.5V)
• < 250 pS skew among CPU and SDRAM clocks.
• < 250 pS skew among PCI clocks.
• Smooth frequency switch with selections from 50 MHz to 83.3 MHz CPU. (W83193R-04)
• Smooth frequency switch with selections from 50 MHz to 112 MHz CPU. (W83193R-04A)
• I C 2-Wire serial interface and .
