ESCRIPTION
The ICS83948I is a low skew, 1-to-12 Differen-
tial-to-LVCMOS Fanout Buffer and a member
of the
HiPerClockS family of High Performance
Clock Solutions from ICS. The ICS83948I has
two selectable clock inputs. The CLK, nCLK
pair can accept most standard differential input levels. The
LVCMOS_CLK can accept LVCMOS or LVTTL input levels.
The low impedance LVCMOS outputs are designed to drive
50
Ω
series or parallel terminated transmission lines. The
effective fanout can be increased from 12 to 24 by utilizing
the ability of the outputs to drive two series terminated lines.
The ICS83948I is characterized at 3.3V core/3.3V output.
Guaranteed output and part-to-part skew characteristics
make the ICS83948I ideal for those clock distribution ap-
plications demanding well defined performance and re-
peatability.
