Product Description
The IMI B9680 is a high fanout system clock buffer. Its
primary application is to create the large quantity of
clocks needed to support a wide range of applications
that
requires
those
clock
loads
signal
that
are
referenced to a single existing clock. Loads of up to 30
pF are supported. The main application of
this
component is to redistribute SDRAM clocks from their
generating devices typically the 440BX chipset to their
loads, the SDRAM modules. The creation of EMI and
the degradation of waveform rise and fall times is
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
EMI is therefore minimized and board layout is
simplified.
