The SN65LVDS047 is a quad differential linedriver

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 four current-mode drivers will

deliver

a

minimum

differential

output

voltage

magnitude of 247 mV into a 100-

Ω load when

enabled.

The intended application of this device and signaling

technique

is

for

point-to-point

and

multi-drop

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.
