3 Description

The SN65LVDS049 device is a dual flow-through

differential line driver-receiver pair that uses low- voltage differential signaling (LVDS) to achieve

signaling rates as high as 400 Mbps. The driver and

receiver electrical interfaces are compliant to the

TIA/EIA-644-A standard.

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 characteristic impedance. 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 application

specific characteristics.

The SN65LVDS049 is characterized for operation

from –40°C to 85°C
