LVDS is defined in the TIA/EIA-644 standard. This improved performance represents the second generation of receiver products for this standard providing a better overall solution for the cabled environment. The next generation family of SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A is an extension to TI's overall product portfolio and is not necessarily a replacement for older LVDS receivers.
Improved features of SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A include an input commonmode voltage range 2 V wider than the minimum required by the standard. This will allow longer cable lengths by tripling the allowable ground noise tolerance to 3 V between a driver and receiver.
Precise control of the differential input voltage thresholds of SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A now allows for inclusion of 50 mV of input voltage hysteresis to improve noise rejection on slowly changing input signals. The input thresholds are still no more than ±50 mV over the full input common-mode voltage range. See Application Information for more details about SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A on this feature.
The high-speed switching of LVDS signals almost always necessitates the use of a line impedance matching resistor at the receiving-end of the cable or transmission media. The SN65LVDT series of receivers eliminates this external resistor by integrating it with the receiver. The nonterminated SN65LVDS series is also available for multidrop or other termination circuits.
The receivers can withstand ±15 kV human-body model (HBM) and ±600 V machine model (MM) electrostatic discharges to the receiver input pins of SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A with respect to ground without damage. This provides reliability in cabled and other connections where potentially damaging noise is always a threat.
The receivers of SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A also include a (patent pending) fail-safe circuit that will provide a high-level output within 500 ns after loss of the input signal. The most common causes of signal loss are disconnected cables, shorted lines, or powered-down transmitters. This prevents noise from being received as valid data under these fault conditions. SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A feature may also be used for wired-OR bus signaling.
The intended application of SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100 W. The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A of the media and the noise coupling to the environment.
The SN65LVDS32A, SN65LVDT32A, SN65LVDS3486A, SN65LVDT3486A, SN65LVDS9637A, and SN65LVDT9637A are characterized for operation from -40°C to 85°C.
