ESCRIPTION
The ICS8344-01 is a low voltage, low skew
fanout buffer and a member of the HiPerClockS鈩?/div>
HiPerClockS鈩?/div>
family of High Performance Clock Solutions from
ICS. The ICS8344-01 is designed to translate any
differential signal levels to LVCMOS levels. The
low impedance LVCMOS outputs are designed to drive 50鈩?/div>
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 output
enable is synchronous which eliminates the runt clock pulses
which occur during asynchronous enabling and disabling of
the outputs. 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.
,&6
Guaranteed output and part-to-part skew characteristics
make the ICS8344-01 ideal for those clock distribution
applications demanding well defined performance and
repeatability.
