PRODUCT DESCRIPTION
The device is a high fanout system clock distributor. Its
primary application is to create the large quantity of
clocks needed to support a wide range of clock loads
that are referenced to a single existing clock. Loads of
up to 30 pF are supported. Primary application 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 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 by using
the IMISC660 to generate the clocks at the target
devices EMI is therefore minimized and board real
estate is saved.
10 output buffers for high clock fanout applications
Each output can be internally disabled for EMI and
power consumption reduction.
Separate power supply for each group of 2 clock
outputs for mixed voltage application.
< 250ps skew between output clocks.
28-pin SSOP package for minimum boad space
Single output Tristate pin for testability
