These circuits are similar to TIA/EIA-644 standard compliant devices (SN65LVDS) counterparts, except that the output current of the drivers is doubled. This modification provides a minimum differential output voltage magnitude of 247 mV across a 50- load simulating two transmission lines in parallel. This allows having data buses with more than one driver or with two line termination resistors. The receivers detect a voltage difference of 50 mV with up to 1 V of ground potential difference between a transmitter and receiver. The intended application of these devices and signaling techniques is point-to-point half duplex, baseband data transmission over a controlled impedance media of approximately 100 characteristic impedance.

The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. DESCRIPTION (CONTINUED) 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, the noise coupling to the environment, and other application-specific characteristics. The SN65LVDM179, SN65LVDM180, SN65LVDM050, and SN65LVDM051 are characterized for operation from -40C to 85C. Table 1.

SLLS324J - DECEMBER 1998 - REVISED JULY 2009 The devices are generally used as building blocks for high-speed point-to-point data transmission. Ground differences are less than 1 V with a low common-mode output and balanced interface for low noise emissions. Devices can interoperate with RS-422, PECL, and IEEE-P1596. Drivers/receivers maintain ECL speeds without the power and dual supply requirements. Transmission Distance - m 1000 30% Jitter 100 5% Jitter 10 1 24 AWG UTP 96 (PVC Dielectric) 0.1 100k 1M 10M 100M Data Rate - Hz Figure 21. Data Transmission Distance Versus Rate FAIL SAFE One of the most common problems with differential signaling applications is how the system responds when no differential voltage is present on the signal pair. The LVDS receiver is like most differential line receivers, in that its output logic state can be indeterminate when the differential input voltage is between -50 mV and 50 mV and within its recommended input common-mode voltage range. TI's LVDS receiver is different; however, in the way it handles the open-input circuit situation. Open-circuit means that there is little or no input current to the receiver from the data line itself. This could be when the driver is in a high-impedance state or the cable is disconnected. When this occurs, the LVDS receiver pulls each line of the signal pair to near VCC through 300-k resistors as shown in Figure 22. The fail-safe feature uses an AND gate with input voltage thresholds at about 2.3 V to VCC - 0.4 V to detect this condition and force the output to a high-level, regardless of the differential input voltage. VCC 300 k 300 k A Rt = 100 (Typ) Y B VIT 2.3 V Figure 22. Open-Circuit Fail Safe of the LVDS Receiver It is only under these conditions that the output of the receiver is valid with less than a 50-mV differential input voltage magnitude. The presence of the termination resistor, Rt, does not affect the fail-safe function as long as it is connected as shown in the figure. Other termination circuits may allow a dc current to ground that could defeat the pullup currents from the receiver and the fail-safe feature.
