W83193R-01
83.MHZ 3-DIMM CLOCK
Publication Release Date: May 1998
Revision 0.20
- 1 -
1.0 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.
The W83193R-02/-04 also provides I
2
C serial bus interface to program the registers to enable or
disable each clock outputs and choose the 0.6% or 1.5% center type spread spectrum.
The W83193R-01 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 1 V /ns slew rate into 30
pF loads. CPU CLOCK outputs typically provide better than 1 V /ns slew rate into 20 pF loads as
maintaining 50
ó
5% duty cycle. The fixed frequency outputs as REF, 24MHz, and 48 MHz provide
better than 0.5V /ns slew rate.
2.0 PRODUCT FEATURES
