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.

Precise control of the differential input voltage thresholds allows for inclusion of 50 mV of input-voltage hysteresis to improve noise rejection. The differential input thresholds are still no more than ±50 mV over the full input common-mode voltage range.

The receiver inputs can withstand ±15 kV human-body model (HBM), with respect to ground, without damage. This provides reliability in cabled and other connections where potentially damaging noise is always a threat.

The intended application of these devices and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100 . The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.

The SN65LVDS349 is characterized for operation from –40°C to 85°C.
