Preliminary W83193R-02/-04/-04A
83.3 MHZ 3-DIMM CLOCK
1.0 GENERAL 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 choose the 0.5% or 1.5% center type spread spectrum.
The W83193R-02/-04/-04A 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 1V /nS slew rate
into 30 pF loads. CPU CLOCK outputs typically provide better than 1V /nS slew rate into 20 pF loads
as maintaining 50
鹵5%
duty cycle. The fixed frequency outputs as REF, 24 MHz, and 48 MHz provide
better than 0.5V /nS slew rate.
