DESCRIPTION

2Z
The
SN65LVDS179,
SN65LVDS180,
SN65LVDS050, and SN65LVDS051 are differential
line drivers and receivers that use low-voltage
differential signaling (LVDS) to achieve signaling
rates as high as 400 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 50-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 depends on the
attenuation characteristics of the media, the noise
coupling to the environment, and other application
specific characteristics).
