duc Description

ro The STLVDS32 is a differential line receiver that

P implements the electrical characteristics of low

te voltage differential signaling (LVDS). This

le signaling technique lowers the output voltage

o levels of 5 V differential standard levels (such as

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

bswitching speeds and allow operations with a

O3.3 V supply rail. This differential receiver

input common mode voltage allows 1 V of ground

potential difference between two LVDS nodes.

The intended application of this device and

signalling technique is both point-to-point and

multidrop 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 depend upon the

attenuation characteristics of the media and noise

coupling to the environment.

The STLVDS32 version is characterized for

operation from -55°C to 125°C.

supply rail. It also provides a valid logical output

state with a ±100 mV differential input voltage

within the input common mode voltage range. The
