DESCRIPTION

The SN65LVDS048A is a quad differential line receiver that implements the electrical characteristics of

low-voltage differential signaling (LVDS). This signaling technique lowers the output voltage levels of 5-V

differential standard levels (such as EIA/TIA-422B) to reduce the power, increase the switching speeds, and

allow operation with a 3.3-V supply rail. Any of the quad differential receivers will provide a valid logical output

state with a ±100-mV differential input voltage within the input common-mode voltage range. The input

common-mode voltage range allows 1 V of ground potential difference between two LVDS nodes

The intended application of this device and signaling technique is for point-to-point baseband data transmission

over controlled impedance media of approximately 100 W. 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, the noise coupling to the environment, and other system characteristics.

The SN65LVDS048A is characterized for operation from –40°C to 85°C.
