Description

The SN65MLVD203B device is a multipoint low-

voltage 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.
