description
The SN55LVDS32, SN65LVDS32,
SN65LVDS3486, and SN65LVDS9637 are
differential line receivers that implement the
electrical characteristics of low-voltage differential
signaling (LVDS). This signaling technique lowers
the output voltage levels of 5-V differential
standard levels (such as EIA/TIA-422B) to reduce
the power, increase the switching speeds, and
allow operation with a 3.3-V supply rail. Any of the
four differential receivers provides a valid logical
output state with a ±100-mV differential input
voltage within the input common-mode voltage
range. The input common-mode voltage range
allows 1 V of ground potential difference between
two LVDS nodes.
The intended application of these devices and
signaling technique is both point-to-point and
multidrop (one driver and multiple receivers) data
transmission over controlled impedance media of
approximately 100 Ω. The transmission media
may be printed-circuit board traces, backplanes,
or cables. The ultimate rate and distance of
data transfer depends on the attenuation
characteristics of the media and the noise
coupling to the environment.
The SN65LVDS32, SN65LVDS3486, and
SN65LVDS9637 are characterized for operation
from −40°C to 85°C. The SN55LVDS32 is
characterized for operation from −55°C to 125°C.
