3 Description
The
SN65MLVD200B,
SN65MLVD202B,
SN65MLVD204B and SN65MLVD205B devices are
multipoint-low-voltage differential (M-LVDS) line
drivers and receivers which are optimized to operate
at signaling rates up to 100 Mbps. This device family
has robust 3.3-V drivers and receivers in the standard
SOIC footprint for demanding industrial applications.
The bus pins are robust to ESD events, with high
levels of protection to human-body model and IEC
contact discharge specifications.
These devices each combine a differential driver and
a differential receiver, which operate from a single
3.3-V supply. The transceivers are optimized to
operate at signaling rates up to 100 Mbps.
The SN65MLVD20xB have enhancements over
similar devices. Improved features include a
controlled slew rate on the driver output to help
minimize reflections from unterminated stubs
resulting in better signal integrity. The same footprint
definition was maintained making for an easy drop-in
replacement for a system performance upgrade. The
devices are characterized for operation from –40°C to
85°C.
