EVM Specifications Value Single-supply voltage range (V– = ground) 2.7 to 5.4 V V± Split-supply voltage range ±1.35 to ±2.7 V IS± Supply current (no load) 1.35 mA Input voltage VS±, Max Output drive ±80 mA IOUT 3 Power Connections The THS4551DGKEVM is equipped with test point connectors for easy connection of power. The positive supply input is red and is labeled V+. The negative supply input is yellow and is labeled V–. The Ground is black and is labeled GND. 3.1 Split-Supply Operation To operate as split supply, apply the positive supply voltage to V+, negative supply voltage to V– , and the ground reference from supply to GND. 3.2 Single-Supply Operation To operate as single supply, connect both the V– connector and the GND connector to ground, and apply the positive supply voltage to V+. Inputs and outputs must be biased per data-sheet specifications for proper operation. The THS4551 output common-mode voltage defaults to mid supply if the Vcm connector is left floating. 2 THS4551DGKEVM SLOU447 – June 2016 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Input and Output Connections www.ti.com 4 Input and Output Connections The THS4551DGKEVM is equipped with SMA connectors for easy connection of signal generators and analysis equipment. As shipped, the EVM is configured for a gain of 1, split supply, single-ended or differential input and single-ended output with 50-Ω termination. For best results, signals must be routed to and from the EVM with cables having 50-Ω characteristic impedance. Either IN+ (J2) or IN– (J1) can be used for single-ended input. The unused connector should be terminated with a 50-Ω resistive SMA load. If no SMA load is available the spaces marked C1 or C2 can be loaded with a 0-Ω resistor to terminate the unused input. Use both IN+ (J2) and IN– (J1) for differential input. OUT+ (J8) is the output connector for single-ended output signals. The amplifier converts the single-ended or differential input to a differential signal at its output pins. A resistor network (R8, R9, R10) and transformer on the output of the amplifier convert the differential output signal to single-ended, and provides a 1-kΩ load to the amplifier when terminated in 50 Ω. A 50-Ω line-impedance match at OUT+ should be preserved. This results in an output measurement loss, and the overall gain is approximately –30 dB. See the THS4551 data sheet applications section (SBOS778), schematics, and layouts for more detail and how to reconfigure the EVM. 4.1 VOCM Input Connections The Vcm input (J3) is optional and the SMA connector is not loaded in default configuration. This input sets the common mode of the output pins. The THS4551 will automatically self-bias the output commonmode voltage to the mid-supply voltage if the Vocm pin is not connected. This is the optimal voltage for maximum output swing and best linearity. The valid range of the VOCM is 0.55 V above the negative supply to 1.5 V below the positive supply. For example, on a ±2.5-V split supply, the Vocm pin can be set anywhere from –1.95 V to 1.0 V. With a single 5-V supply the valid range would be 0.55 V to 3.5 V. Remember, the outputs of the THS4551 can swing from rail to rail; however, the maximum output swing available is reduced when the VOCM pin is set to a voltage other than mid supply. If providing 50-Ω termination for the Vcm input signal source is desired, C6 can be replaced with a 0-Ω resistor. The board is shipped with C6 populated with 0.22 µF and VOCM input is set to mid-supply voltage with C6 populated. 4.2 PD Input Connections The PD jumper (J5) allows the THS4551 to be disabled. An SMA connector can also be loaded at J4 and a signal for the power down function can be applied for high-speed testing. Normally the J5 jumper is used to enable or disable (power down) the amplifier. When jumper J5 is open, the amplifier is not powered down, so it is enabled. When the shorting block is connected and J5 is closed, the amplifier is powered down. For high-speed testing, the C4 can be replaced with 0 Ω to terminate the PD SMA input. The shorting block should be removed from J5 during high-speed testing. Because 0 Ω at C4 terminates to the ground and not to the supplies. The state of the amplifier will be undefined when the signal source is disconnected. For this reason, 0 Ω at C4 should only be used when driving the SMA connector with a high speed, controlled impedance source. 4.3 Using the Optional Differential Outputs (J6, J7) The THS4551DGKEVM can be reconfigured for fully-differential outputs. By removing resistors R19 and R20, the balun circuit is disconnected from the amplifier output. If 50-Ω resistors are loaded in the R26 and R27 resistor positions, and SMA connectors are loaded in the J6 and J7 connector positions, J6 and J7 can be used for fully-differential output signals. If 50-Ω test equipment is connected to J6 and J7, the total load to the amplifier is 200 Ω. The data-sheet specifications were produced with a 1-kΩ load. In order to match a 1-kΩ load, load R26 and R27 with 475-Ω resistors, and then load R25 and R28 with 56.2-Ω resistors.

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.
