Product Description
The IMIB9688 is a high fanout system clock buffer.
Loads of up to 30 pF are supported. One of the chief
applications of this component is where long traces are
used to transport clocks from their generating devices
to their loads. The creation of EMI and the degradation
of waveform rise and fall times are greatly reduced by
running a single reference clock trace to this device and
then using it to regenerate the clock that drives shorter
traces. Using these devices, the EMI is therefore
minimized, and board real estate is saved.
