TYPICAL APPLICATION
Figure 20. Point-to-Point Application
APPLICATIONS INFORMATION
LVDS drivers and receivers are intended to be primarily used in an uncomplicated point-to-point configuration as
is shown in Figure 20. This configuration provides a clean signaling environment for the quick edge rates of the
drivers. The receiver is connected to the driver through a balanced media which may be a standard twisted pair
cable, a parallel pair cable, or simply PCB traces. Typically the characteristic impedance of the media is in the
range of 100Ω. A termination resistor of 100Ω should be selected to match the media, and is located as close to
the receiver input pins as possible. The termination resistor converts the current sourced by the driver into a
voltage that is detected by the receiver. Other configurations are possible such as a multi-receiver configuration,
but the effects of a mid-stream connector(s), cable stub(s), and other impedance discontinuities as well as
ground shifting, noise margin limits, and total termination loading must be taken into account.
The DS90C032 differential line receiver is capable of detecting signals as low as 100 mV, over a ±1V common-
mode range centered around +1.2V. This is related to the driver offset voltage which is typically +1.2V. The
driven signal is centered around this voltage and may shift ±1V around this center point. The ±1V shifting may be
the result of a ground potential difference between the driver's ground reference and the receiver's ground
reference, the common-mode effects of coupled noise, or a combination of the two. Both receiver input pins
should honor their specified operating input voltage range of 0V to +2.4V (measured from each pin to ground),
exceeding these limits may turn on the ESD protection circuitry which will clamp the bus voltages.
Receiver Failsafe
The LVDS receiver is a high gain, high speed device that amplifies a small differential signal (20mV) to CMOS
logic levels. Due to the high gain and tight threshold of the receiver, care should be taken to prevent noise from
appearing as a valid signal.
The receiver’s internal failsafe circuitry is designed to source/sink a small amount of current, providing failsafe
protection (a stable known state of HIGH output voltage) for floating and terminated (100Ω) receiver inputs in low
noise environment (differential noise < 10mV).
•
Open Input Pins
TheDS90C032 is a quad receiver device, and if an application requires only 1, 2 or 3 receivers, the unused
channel(s) inputs should be left OPEN. Do not tie unused receiver inputs to ground or any other voltages.
The input is biased by internal high value pull up and pull down resistors to set the output to a HIGH state.
This internal circuitry will ensure a HIGH, stable output state for open inputs.
•
Terminated Input
The DS90C032 requires external failsafe biasing for terminated input failsafe.
Terminated input failsafe is the case of a receiver that has a 100Ω termination across its inputs and the driver
is in the following situations. Unplugged from the bus, or the driver output is in TRI-STATE or in power-off
condition. The use of external biasing resistors provide a small bias to set the differential input voltage while
the line is un-driven, and therefore the receiver output will be in HIGH state. If the driver is removed from the
bus but the cable is still present and floating, the unplugged cable can become a floating antenna that can
pick up noise. The LVDS receiver is designed to detect very small amplitude and width signals and recover
them to standard logic levels. Thus, if the cable picks up more than 10mV of differential noise, the receiver
may respond. To insure that any noise is seen as commonmode and not differential, a balanced interconnect
and twisted pair cables is recommended, as they help to ensure that noise is coupled common to both lines
and rejected by the receivers.

SNLS203D –MARCH 2006–REVISED APRIL 2013
TI recommends external failsafe biasing on its LVDS receivers for a number of system level and signal quality
reasons. First, only an application that requires failsafe biasing needs to employ it. Second, the amount of
failsafe biasing is now an application design parameter and can be custom tailored for the specific
application. In applications in low noise environments, they may choose to use a very small bias if any. For
applications with less balanced interconnects and/or in high noise environments they may choose to boost
failsafe further. TI's "LVDS Owner’s Manual provides detailed calculations for selecting the proper failsafe
biasing resistors. Third, the common-mode voltage is biased by the resistors during the un-driven state. This
is selected to be close to the nominal driver offset voltage (VOS). Thus when switching between driven and
un-driven states, the common-mode modulation on the bus is held to a minimum.
For additional Failsafe Biasing information, please refer to Application Note AN-1194 (SNLA051) for more
detail.

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)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
Multiple Top-Side Markings will be inside parentheses. Only one Top-Side Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a
continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
