ICS9179BF-03LFT
General Description
The ICS9179-03 generates low skew clock buffers required
for high speed RISC or CISC microprocessor systems such as
Intel PentiumPro. Outputs will handle up to 133MHz clocks.
An output enable is provided for testability.
The device is a buffer with low output to output skew. This is
a Fanout buffer device, not using an internal PLL. This buffer
can also be a feedback to an external PLL stage for phase
synchronization to a master clock. There are a total of ten
outputs, sufficient for feedback to a PLL source and to drive
four small outline DIMM modules (S.O. DIMM) at 2 clocks
each. Or a total of ten outputs as a Fanout buffer from a
common clock source.
The individual clock outputs are addressable through I
be enabled, or stopped in a low state for reduced EMI when
the lines are not needed.
