3 Description
The SN65MLVD203B device is a multipoint lowvoltage
differential signaling (M-LVDS) line driver and
receiver which is optimized to operate at signaling
rates up to 200 Mbps. This device has a robust 3.3-V
driver and receiver in the standard QFN 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.
The device combines a differential driver and a
differential receiver (transceiver), which operates from
a single 3.3-V supply. The transceiver is optimized to
operate at signaling rates up to 200 Mbps.
The SN65MLVD203B has 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 devices are characterized for operation
from –40°C to 125°C.
The SN65MLVD203B M-LVDS transceiver is part of
the TI extensive M-LVDS portfolio.
