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- 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.
