DESCRIPTIONThe STLVDS31 and STLVDS3487 are 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 100Ω load when enabled.
The indended application of this device and
signalling tecnique is for point-to-point baseband
data transmission over controlled impedance
media approximately 100Ω. 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 enviroment.
The STLVDS31 and STLVDS3487 are
characterized for operation from -40°C to 85°C .
