To ensure fastest propagation delay and minimum skew, clock input edge rates should not be slower than 1 ns/V; control signals not slower than 3 ns/V.

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 to100Ω. 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 discontinuities as well as ground shifting, noise margin limits, and total termination loading must be taken into account. The DS92CK16 differential line driver is a balanced current source design. A current mode driver, generally speaking has a high output impedance (100 ohms) and supplies a constant current for a range of loads (a voltage mode driver on the other hand supplies a constant voltage for a range of loads). 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 9.330 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 9.33 mA loop current will develop a differential voltage of about 350mV across 37.5Ω (double terminated 75Ω differential transmission backplane) effective resistance, which the receiver detects with a 280 mV minimum differential noise margin neglecting resistive line losses (driven signal minus receiver threshold (350 mV – 70 mV = 280 mV)). The signal is centered around +1.2V (Driver Offset, VOS) with respect to ground. Note that the steady-state voltage (VSS) peak-to-peak swing is twice the differential voltage (VOD) and is typically 700 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. POWER DECOUPLING RECOMMENDATIONS Bypass capacitors must be used on power pins. High frequency ceramic (surface mount is recommended) 0.1µF in parallel with 0.01µF, in parallel with 0.001µF at the power supply pin as well as scattered capacitors over the printed circuit board. Multiple vias should be used to connect the decoupling capacitors to the power planes. A 4.7µF (35V) or greater solid tantalum capacitor should be connected at the power entry point on the printed circuit board. PC BOARD CONSIDERATIONS Use at least 4 PCB layers (top to bottom); BLVDS signals, ground, power, TTL signals. Isolate TTL signals from BLVDS signals, otherwise the TTL may couple onto the BLVDS lines. It is best to put TTL and BLVDS signals on different layers which are isolated by a power/ground plane(s). Keep drivers and receivers as close to the (BLVDS port side) connectors as possible to create short stub lengths.

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 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 or vias and other discontinuities on the line. Avoid 90° turns (these cause impedance discontinuities). 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 discontinuities 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 DS92CK16 BLVDS output is 0.75ns (20% to 80%). The 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(SNLA035) and AN–808(SNLA028)). TERMINATION Use a resistor which best matches the differential impedance of your loaded transmission line. Remember that the current mode outputs need the termination resistor to generate the differential voltage. BLVDS will not work without resistor termination. Surface mount 1% to 2% resistors are best. PROBING BLVDS TRANSMISSION LINES Always use high impedance (> 100kΩ), low capacitance (< 2pF) scope probes with a wide bandwidth (1GHz) scope. Improper probing will give deceiving results. CABLES AND CONNECTORS, GENERAL COMMENTS Use controlled impedance media. The connectors you use should have a matched differential impedance of about Zo Ω. They should not introduce major impedance discontinuities. Balanced cables (e.g. twisted pair) are usually better than unbalanced cables (ribbon cable, simple coax.) for noise reduction and signal quality. Balanced cables tend to generate less EMI due to field canceling effects and also tend to pick up electromagnetic radiation a common-mode (not differential mode) noise which is rejected by the receiver. For cable distances < 0.5M, most cables can be made to work effectively. For distances 0.5M ≤ d ≤ 10M, CAT 3 (category 3) twisted pair cable works well, is readily available and relatively inexpensive. 10 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: DS92CK16 DS92CK16 www.ti.com SNAS044C – NOVEMBER 1999 – REVISED APRIL 2013 REVISION HISTORY Changes from Revision B (April 2013) to Revision C • Page Changed layout of National Data Sheet to TI format .......................................................................................................... 10 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: DS92CK16 11 PACKAGE OPTION ADDENDUM www.ti.com 13-Apr-2013 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan Lead/Ball Finish (2) MSL Peak Temp Op Temp (°C) Top-Side Markings (3) (4) DS92CK16TMTC ACTIVE TSSOP PW 24 61 TBD Call TI Call TI -40 to 85 DS92CK16T MTC DS92CK16TMTC/NOPB ACTIVE TSSOP PW 24 61 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 85 DS92CK16T MTC DS92CK16TMTCX ACTIVE TSSOP PW 24 2500 TBD Call TI Call TI -40 to 85 DS92CK16T MTC DS92CK16TMTCX/NOPB ACTIVE TSSOP PW 24 2500 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 85 DS92CK16T MTC (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.

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.
