DESCRIPTION
The SN65LVDS179, SN65LVDS180, SN65LVDS050,
and SN65LVDS051 are differential line drivers and
receivers that use low-voltage differential signaling
(LVDS) to achieve signaling rates as high as 400
Mbps. The TIA/EIA-644 standard compliant electrical
interface provides a minimum differential output
voltage magnitude of 247 mV into a 100-Ω load and
receipt of 50-mV signals with up to 1 V of ground
potential difference between a transmitter and
receiver.
The intended application of this device and signaling
technique is for point-to-point 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).

DESCRIPTION (CONTINUED)
The devices offer various driver, receiver, and enabling combinations in industry standard footprints. Since these
devices are intended for use in simplex or distributed simplex bus structures, the driver enable function does not
put the differential outputs into a high-impedance state but rather disconnects the input and reduces the
quiescent power used by the device. (For these functions with a high-impedance driver output, see the
SN65LVDM series of devices.) All devices are characterized for operation from −40°C to 85°C.

APPLICATION INFORMATION
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.

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 -100 mV and 100 mV
and within its recommended input common-mode voltage range. TI's LVDS receiver is different in how it handles
the open-input circuit situation, however.
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-kΩ resistors as shown in Figure 11. 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.

It is only under these conditions that the output of the receiver will be valid with less than a 100-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.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
