DESCRIPTION
The STLVDS050 is differential line drivers and
receivers
that
use
low-voltage
differential
signaling (LVDS) to achieve signaling rate as high
as 400Mbps.
The EIA/TIA-644 standard compliant electrical
interface provides a minimum differential output
voltage magnitude of 247 mV into a 100
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 an
signaling technique is for point-to-point baseband
data transmission over controlled impedance
media of approximately 100
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).
