BLVDS drivers and receivers are intended to be used in a differential backplane configuration. Transceivers or receivers are connected to the driver through a balanced media such as differential PCB traces. Typically, the characteristic differential impedance of the media (Zo) is in the range of 50Ω to 100Ω. Two termination resistors of ZoΩ each are placed at the ends of the transmission line backplane. The termination resistor converts the current sourced by the driver into a voltage that is detected by the receiver. The effects of mid-stream connector(s), cable stub(s), and other impedance discontinuity as well as ground shifting, noise margin limits, and total termination loading must be taken into account. The DS92LV040A differential line driver is a balanced current mode design. A current mode driver, generally speaking has a high output impedance (100 ohms) and supplies a reasonably constant current for a range of loads (a voltage mode driver on the other hand supplies a constant voltage for a range of loads). The current is switched through the load in one direction to produce a logic state and in the other direction to produce the other logic state. The output current is typically 12 mA. The current changes as a function of load resistor. The current mode requires (as discussed above) that a resistive termination be employed to terminate the signal and to complete the loop. Unterminated configurations are not allowed. The 12 mA loop current will develop a differential voltage of about 300mV across a 27Ω (double terminated 54Ω differential transmission backplane) effective resistance, which the receiver detects with a 230 mV minimum differential noise margin neglecting resistive line losses (driven signal minus receiver threshold (300 mV – 70 mV = 230 mV)). The signal is centered around +1.2V (Driver Offset, VOS ) with respect to ground. Note that the steady-state voltage (VSS ) peak-topeak swing is twice the differential voltage (VOD ) and is typically 600 mV. The current mode driver provides substantial benefits over voltage mode drivers, such as an RS-422 driver. Its quiescent current remains relatively flat versus switching frequency. Whereas the RS-422 voltage mode driver increases exponentially in most case between 20 MHz–50 MHz. This is due to the overlap current that flows between the rails of the device when the internal gates switch. Whereas the current mode driver switches a fixed current between its output without any substantial overlap current. This is similar to some ECL and PECL devices, but without the heavy static ICC requirements of the ECL/PECL designs. LVDS requires 80% less current than similar PECL devices. AC specifications for the driver are a tenfold improvement over other existing RS-422 drivers. The TRI-STATE function allows the driver outputs to be disabled, thus obtaining an even lower power state when the transmission of data is not required. There are a few common practices which should be implied when designing PCB for Bus LVDS signaling. Recommended practices are: • Use at least 4 PCB board layer (Bus LVDS signals, ground, power and TTL signals). • Keep drivers and receivers as close to the (Bus LVDS port side) connector as possible. • Bypass each Bus LVDS device and also use distributed bulk capacitance between power planes. Surface mount capacitors placed close to power and ground pins work best. Three or more high frequency, multi-layer ceramic (MLC) surface mount (0.1 µF, 0.01 µF, 0.001 µF) in parallel should be used between each VCC and ground. – Multiple vias should be used to connect VCC and Ground planes to the pads of the by-pass capacitors. – In addition, it may be necessary to randomly distribute by-pass capacitors of different values (200pF to 1000pF) to achieve different resonant frequencies. • Use the termination resistor which best matches the differential impedance of your transmission line. • Leave unused Bus LVDS receiver inputs open (floating). Limit traces on unused inputs to <0.5 inches. • Isolate TTL signals from Bus LVDS signals MEDIA (CONNECTOR or BACKPLANE) SELECTION: • The backplane and connectors should have a matched differential impedance. Use controlled impedance traces which match the differential impedance of your transmission medium (ie. backplane or cable) and termination resistor(s). Run the differential pair trace lines as close together as possible as soon as they leave the IC . This will help eliminate reflections and ensure noise is coupled as common-mode. In fact, we have seen that differential signals which are 1mm apart radiate far less noise than traces 3mm apart since magnetic field cancellation is much better with the closer traces. Plus, noise induced on the differential lines is much more likely to appear as common-mode which is rejected by the receiver. Match electrical lengths between traces to reduce skew. Skew between the signals of a pair means a phase difference between Submit Documentation Feedback Copyright © 2001–2013, Texas Instruments Incorporated Product Folder Links: DS92LV040A 5 DS92LV040A SNOS521D – JANUARY 2001 – REVISED APRIL 2013 • www.ti.com signals which destroys the magnetic field cancellation benefits of differential signals and EMI will result. (Note the velocity of propagation, v = c/Er where c (the speed of light) = 0.2997mm/ps or 0.0118 in/ps). Do not rely solely on the autoroute function for differential traces. Carefully review dimensions to match differential impedance and provide isolation for the differential lines. Minimize the number of vias and other discontinuity on the line. Avoid 90° turns (these cause impedance discontinuity). Use arcs or 45° bevels. Within a pair of traces, the distance between the two traces should be minimized to maintain common-mode rejection of the receivers. On the printed circuit board, this distance should remain constant to avoid discontinuity in differential impedance. Minor violations at connection points are allowable. Stub Length: Stub lengths should be kept to a minimum. The typical transition time of the DS92LV040A BLVDS output is 0.75ns (20% to 80%). The extrapolated 100 percent time is 0.75/0.6 or 1.25ns. For a general approximation, if the electrical length of a trace is greater than 1/5 of the transition edge, then the trace is considered a transmission line. For example, 1.25ns/5 is 250 picoseconds. Let velocity equal 160ps per inch for a typical loaded backplane. Then maximum stub length is 250ps/160ps/in or 1.56 inches. To determine the maximum stub for your backplane, you need to know the propagation velocity for the actual conditions (refer to application notes AN 905 and AN 808).

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.
