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 Ω. 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.
