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.

JUNE 2003 APPLICATION INFORMATION Type-1 and Type-2 receivers The M-LVDS standard defines Type-1 and Type-2 receivers. Type-1 receivers include no provisions for failsafe and have their differential input voltage thresholds near zero volts. Type-2 receivers have their differential input voltage thresholds offset from zero volts to detect the absence of a voltage difference. Type-1 receivers maximize the differential noise margin and are intended for maximum signaling rates. Type-2 receivers are intended for control signals and slower signaling rates. The impact on receiver output by the offset input can be seen in Table 3 and Figure 33. Table 3. M-LVDS Receiver Input Voltage Threshold Requirements VID – Differential Input Voltage – mV 200 Receiver Type Output Low Output High 1 –2.4 V ≤ VID ≤ –0.05 V 0.05 V ≤ VID ≤ 2.4 V 2 –2.4 V ≤ VID ≤ 0.05 V 0.15 V ≤ VID ≤ 2.4 V Type 1 Type 2 High 150 100 High 50 0 Low –50 –100 Low Transition Regions Figure 33.

The two standards define balanced multipoint systems with some basic architecture changes due to the different applications. Table 4 gives a high-level comparison of the two different technologies. Table 4. Comparison Between M-LVDS and RS-485 Standards Number of Loads Differential Voltage Range Common-Mode Voltage Range Maximum Signaling Rate (Mbps) Receiver Minimum Threshold RS-485 32 1.5 V to 5 V –7 V to 12 V 50 Mbps ±200 mV M-LVDS 32 480 mV to 650 mV –1 V to 3.4 V 500 Mbps ±50 mV It can be seen that with the greater differential output voltage and common-mode voltage range of the RS-485-type device, it can handle longer signaling distances where M-LVDS offers ten times the signaling rate of RS-485.
