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.
