The SN65MLVD20xA family of devices are multipoint-low-voltage differential (M-LVDS) line drivers and receivers that are optimized to operate at signaling rates up to 100 Mbps. All parts comply with the 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. The driver output has been designed to support multipoint buses presenting loads as low as 30 Ω and incorporates controlled transition times to allow for stubs off of the backbone transmission line.
These devices have Type-1 and Type-2 receivers that detect the bus state with as little as 50 mV (for Type-1) or 150 mV (for Type-2) of differential input voltage over a common-mode voltage range of –1 V to 3.4 V. The Type-1 receivers exhibit 25 mV of differential input voltage hysteresis to prevent output oscillations with slowly changing signals or loss of input. Type-2 receivers include an offset threshold to provide a known output state under open-circuit and bus-idle fault conditions.
This family of devices operates and meets all the specified performance requirements for supply voltages in the range of 3 V to 3.6 V. When the supply voltage drops below 1.5 V (or is turning on and has not yet reached 1.5 V), power-on reset circuitry sets the driver output to a high-impedance state.
The bus terminals of the SN65MLVD20xA devices possess on-chip ESD protection against ±8-kV human body model (HBM) and ±8 kV.
