SN75LVDS050, and SN75LVDS051 are differen-
tial line drivers and receivers that use low-voltage
differential signaling (LVDS) to achieve signaling
rates as high as 155 Mbps. The TIA/EIA-644
standard compliant electrical interface provides a
minimum differential output voltage magnitude of
247 mV into a 100 Ω load and receipt of 100 mV
signals with up to 1 V of ground potential
difference between a transmitter and receiver.

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. (Note: 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).
