description
This series of SN65MLVD20x devices are low-voltage differential line drivers and receivers complying with the
proposed multipoint low-voltage differential signaling (M-LVDS) standard (TIA/EIA–899). These circuits are
similar to their TIA/EIA-644 standard compliant LVDS counterparts, with added features to address multipoint
applications. Driver output current has been increased to support doubly-terminated, 50-Ω load multipoint
applications. Driver output slew rates are optimized for signaling rates up to 100 Mbps.
Types 1 and 2 receivers are available. Both types of receivers operate over a common-mode voltage range of
–1 V to 3.4 V to provide increased noise immunity in harsh electrical environments. Type-1 receivers have their
differential input voltage thresholds near zero volts (±50 mV), and include 25 mV of hysteresis to prevent output
oscillations in the presence of noise. Type-2 receivers include an offset threshold to detect open-circuit, idle-bus,
and other fault conditions, and provide a known output state under these conditions.
The intended application of these devices is in half-duplex or multipoint baseband data transmission over
controlled impedance media of approximately 100-Ω characteristic impedance. The transmission media may
be printed circuit board traces, backplanes, or cables. (Note: The ultimate rate and distance of data transfer is
dependent upon the attenuation characteristics of the media, the noise coupling to the environment, and other
application-specific characteristics).
These devices are characterized for operation from –40°C to 85°C.
