LOW SKEW, 1-TO-12 DIFFERENTIAL-
TO-LVCMOS/LVTTL FANOUT BUFFER
ICS83948I-147
IDT / ICS LVCMOS/LVTTL CLOCK GENERATOR

ICS83948AYI-147 REV. C JANUARY 15, 2008
General Description
The ICS83948I-147 is a low skew, 1-to-12
Differential-to-LVCMOS/LVTTL Fanout Buffer and
a member of the HiPerClockSfamily of High
Performance Clock Solutions from IDT. 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 outputs 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 performance and
repeatability.
