WWW.TI.COM 1 SLLS490B − MARCH 2001 − REVISED NOVEMBER 2004 description (continued) The receivers can withstand ±15 kV human-body model (HBM) and ±600 V machine model (MM) electrostatic discharges to the receiver input pins with respect to ground without damage. This provides reliability in cabled and other connections where potentially damaging noise is always a threat. The receivers also include a (patent pending) failsafe circuit that will provide a high-level output within 600 ns after loss of the input signal. The most common causes of signal loss are disconnected cables, shorted lines, or powered-down transmitters. The failsafe circuit prevents noise from being received as valid data under these fault conditions. This feature may also be used for Wired-Or bus signaling. See The Active Failsafe Feature of the SN65LVDS32B application note. The intended application and signaling technique of these devices is point-to-point baseband data transmission over controlled impedance media of approximately 100 Ω. 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 of the media and the noise coupling to the environment. The SN65LVDS33, SN65LVDT33, SN65LVDS34 and SN65LVDT34 are characterized for operation from −40°C to 85°C.

Current LVDS failsafe solutions require either external components with subsequent reductions in signal quality or integrated solutions with limited application. This family of receivers has a new integrated failsafe that solves the limitations seen in present solutions. A detailed theory of operation is presented in application note The Active Failsafe Feature of the SN65LVDS32B, literature number SLLA082A. The following figure shows one receiver channel with active failsafe. It consists of a main receiver that can respond to a high-speed input differential signal. Also connected to the input pair are two failsafe receivers that form a window comparator. The window comparator has a much slower response than the main receiver and it detects when the input differential falls below 80 mV. A 600-ns failsafe timer filters the window comparator outputs. When failsafe is asserted, the failsafe logic drives the main receiver output to logic high.

Designers know of the established technology and that it is capable of high-speed data transmission. In the past, system requirements often forced the selection of ECL. Now technologies like LVDS provide designers with another alternative. While the total exchange of ECL for LVDS may not be a design option, designers have been able to take advantage of LVDS by implementing a small resistor divider network at the input of the LVDS receiver. TI has taken the next step by introducing a wide common-mode LVDS receiver (no divider network required) which can be connected directly to an ECL driver with only the termination bias voltage required for ECL termination (VCC – 2 V). Figures 14 and 15 show the use of an LV/PECL driver driving 5 meters of CAT−5 cable and being received by TI’s wide common-mode receiver and the resulting eye-pattern. The values for R3 are required in order to provide a resistor path to ground for the LV/PECL driver. With no resistor divider, R1 simply needs to match the characteristic load impedance of 50 Ω. The R2 resistor is a small value and is intended to minimize any possible common-mode current reflections.
