W83193R-04 Description
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 the registers to enable or disable each clock outputs and...
