ICS83948I-147
LOW SKEW, 1-TO-12
DIFFERENTIAL-TO-LVCMOS/LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83948I-147 is a low skew, 1-to-12
Differential-to-LVCMOS/LVTTL Fanout Buffer and
a member of the HiPerClockS family of High
Performance Clock Solutions from ICS. The
ICS83948I-147 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/LVTTL out-
puts are designed to drive 50
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-147 is characterized at full 3.3V or full 2.5V
operating supply modes. Guaranteed output and part-to-part
skew characteristics make the ICS83948I-147 ideal for those
clock distribution applications demanding well defined per-
formance and repeatability.
