DESCRIPTION
The SN65LVDS349 is a high-speed, quadruple
differential receiver with a wide common-mode input
voltage range. This allows receipt of TIA/EIA-644
signals with up to 3-V of ground noise or a variety of
differential and single-ended logic levels. The '349 is
in a 16-pin package to match the industry-standard
footprint of the DS90LV048. The '349 offers a
flow-through architecture with all inputs on one side
and outputs on the other to ease board layout and
reduce crosstalk between receivers.
The LVDS349 provides 3x the standard's minimum
common-mode noise voltage tolerance. The -4 V to
5 V common-mode range allows usage in harsh
operating environments or accepts LVPECL, PECL,
LVECL, ECL, CMOS, and LVCMOS levels without
level shifting circuitry. See the Application Information
Section for more details on the ECL/PECL to LVDS
interface.
