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.
