3 Description
The SN55LVRA4-SEP offers the widest commonmode
input voltage range in the industry. These
receivers provide an input voltage range specification
compatible with a 5V PECL signal as well as an
overall increased ground-noise tolerance.
The SN55LVRA4-SEP include a failsafe circuit that
provides a high-level output within 60ns after loss
of the input signal. The most common causes of
signal loss are disconnected cables, shorted lines,
or powered-down transmitters. The failsafe circuit
prevents noise from being received as valid data
under these fault conditions.
The intended application and signaling technique
of these devices is point-to-point baseband data
transmission over controlled impedance media of
approximately 100Ω. The transmission media can 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 the noise coupling to the environment.
The SN55LVRA4-SEP is characterized for operation
from –55°C to 125°C.
