DESCRIPTION

The STLVDS31 is a quad differential line drivers

that implements the electrical characteristics of

low voltage differential signaling (LVDS). This

signaling technique lowers the output voltage

levels of 5V differential standard levels (such as

TIA/EIA-422B) to reduce the power, increase the

switching speeds and allows operations with a

3.3V supply rail. Any of the four current mode

drivers will deliver a minimum differential output

voltage magnitude of 247mV into a 100

Ω load

when enabled.

The intended application of this device and

signalling technique is for point-to-point baseband

data transmission over controlled impedance

media 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 and noise

coupling to the environment.

The STLVDS31 is characterized for operation

from -40°C to 85°C.
