ICS83940-01
LOW SKEW, 1-TO-18
DIFFERENTIAL-TO-LVCMOS FANOUT BUFFER
PRELIMINARY
GENERAL DESCRIPTION
The ICS83940-01 is a low skew, 1-to-18 Differ-
ential-to-LVCMOS Fanout Buffer and a member
of the HiPerClockS family of High Performance
Clock Solutions from ICS. The 83940-01 has two
selectable clock inputs. The CLK0, nCLK0 pair
can accept most standard differential input levels. The single
ended clock input accepts LVCMOS or LVTTL input levels.
The low impedance LVCMOS outputs are designed to drive
50
series or parallel terminated transmission lines. The ef-
fective fanout can be increased from 18 to 36 by utilizing the
ability of the outputs to drive two series terminated lines.
The ICS83940-01 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 ICS83940 ideal for those clock distribution applica-
tions demanding well defined performance and repeatability.
