ESCRIPTION
The ICS8344-01 is a low voltage, low skew
fanout buffer and a member of the HiPerClockS
family of High Performance Clock Solutions from
ICS. The ICS8344-01 has two selectable clock
inputs. The CLK0, nCLK0 and CLK1, nCLK1 pairs
can accept most standard differential input levels. The
ICS8344-01 is designed to translate any differential signal
levels to LVCMOS levels. The low impedance LVCMOS out-
puts are designed to drive 50
series or parallel terminated
transmission lines. The effective fanout can be increased to
48 by utilizing the ability of the outputs to drive two series
terminated lines. Redundant clock applications can make use
of the dual clock input. The dual clock inputs also facilitate
board level testing. The clock enable is internally synchro-
nized to eliminate runt pulses on the outputs during asyn-
chronous assertion/deassertion of the clock enable pin. The
outputs are driven low when disabled. The ICS8344-01 is
characterized at full 3.3V, full 2.5V and mixed 3.3V input and
2.5V output operating supply modes.
Guaranteed output and part-to-part skew characteristics
make the ICS8344-01 ideal for those clock distribution
applications demanding well defined performance and
repeatability.
