ICS83948AYI-147 REV. D NOVEMBER 1, 2012
General Description
The ICS83948I-147 is a low skew, 1-to-12 Differential-to-LVC-
MOS/LVTTL Fanout Buffer. The ICS83948I-147 has two select-
able 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 trans-
mission 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, full 2.5V or mixed
3.3V core/2.5V output 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.
