This section outlines the various component configurations. Based on the configuration, testing and board setup must be altered to accommodate the given components and features. 1.1 DAC Component The TSW3070EVM uses the 1-GSPS LVDS DAC5682Z with a current sink output. 1.2 Board Configuration The analog output of the DAC employs a current sink structure which requires the dc common mode of the DAC to be kept at 3.3 V with a maximum compliance voltage at 3.8 V and a minimum voltage at 2.8 V. The resistor bias network between the DAC5682Z and the OPA695 or THS3095 assume that the DAC has maximum current set at 20 mA. For the OPA695 output stage, this network combined with the filter termination provides a combined ac impedance of about 25 Ω, resulting in a maximum voltage of 500 mVpp on each DAC output pin. For the THS3091 and THS3095, the network is different and provides a combined 50-Ω load, resulting in a 1-Vpp signal on each of the DAC output pins. By design, in order to preserve the proper dc levels, the DAC coarse gain should be kept at the maximum (15), though deviation by a few steps is generally acceptable with no degradation in performance. The OPA circuits have been designed to have a combined output gain of 2.2x, whereas the THS3091 and THS3095 circuit has a gain of 3.3x. The resistor networks and gain can be modified as necessary for custom applications. However, special care must be taken to ensure that the 3.3-Vdc common mode voltage is maintained at the DAC output and the DAC compliance voltages are met. 1.2.1 Using Optional Passive Transformer Output The resistor network can be configured such that the DAC output is routed to a transformer which enables measurements of the DAC output to be made using a passive transformer output. Either of the outputs can be configured for this (see Section 9). 1.2.2 Using External Operational Amplifier Supplies By default, both amplifiers are set up to operate with a ±5 V. This is adequate in most cases for evaluation purposes. However, both the OPA695 and THS3095 can be operated at higher voltages; the OPA can be used with a ±6-V supply, and the THS3095 can be used with a ±15-V supply. Ferrite beads allow the use of a different ±Vamp supply for both amplifiers. If the THS3095 is being evaluated at voltages higher than ±6 V, the OPA695 power ferrite beads should be removed to isolate the OPA695 from the higher supply voltages (see Section 9). 1.3 VCXO The CDCM7005 requires a VCXO source to derive its output clock signals. The VCXO is at reference designator U6. There is an onboard 10-MHz reference as well as an onboard 800-MHz VCXO. These can be locked together using the CDCM7005 with the appropriate programming via the DAC5682Z GUI. An external VCXO clock source can be used. In this mode, the CDCM7005 only acts as a clock divider or buffer to provide the necessary clocks to the TSW3100 LVDS pattern generator, and sampling clock to the DAC5682Z.

Block Diagram 3 Key Texas Instruments Components 3.1 CDCM7005 The CDCM7005 clock distribution integrated circuit (IC) is used to generate and synchronize the clock outputs to the system. The device has five outputs which can be either LVPECL or LVCMOS and can be divided down by 1, 2, 3, 4, 6, 8, and 16. The divide by 16 can be replaced with a divide by 4 or 8 with a 90 degree phase shift, if desired. This device is used to lock the onboard 800-MHz VCXO and 10-MHz reference. For further information about the CDCM7005 device, see the device data sheet, SCAS793. 3.2 DAC5682Z The DAC5682Z is a 16-bit interpolating dual digital-to-analog converter (DAC) with a high-speed LVDS data interface. The device incorporates a digital complex coarse mixer, independent differential offset control, and I/Q amplitude control. The device can be used with excellent results in baseband mode, low IF mode, and high IF mode. The digital circuits can be manipulated such that it has the functionality of a DAC5681. For further information about the DAC5682Z device, see the device datasheet, SLLS853. 3.3 TPS76xxx, TPS5430, UCC284-5 The TPS76xxx devices provide 1.8-V, 3.3-V, and 5-V linear regulation for the DAC5682Z, CDCM7005, and V+ amplifier supplies. The TPS5430 generate –5.5 V from 6-V input followed by the UCC284-5 which provides linear -5-V regulation for the V– amplifier supply. More information about the TPS5430 and UCC284-5 devices is found in the respective datasheets, SLVS632 and SLUS234. 4 TSW3070EVM: Amplifier Interface to Current Sink DAC - Arbitrary Waveform Generator Demonstration Copyright © 2008–2016, Texas Instruments Incorporated SLWU055A – May 2008 – Revised May 2016 Submit Documentation Feedback Key Texas Instruments Components www.ti.com 3.4 OPA695, THS3091, THS30915 These both provide the differential-to-single-ended conversion for the DAC5682Z output. The OPA695 is a wide bandwidth (1400 MHz) high-performance operational amplifier (see data sheet SBOS693). The THS3095 is high-performance operational amplifier capable of driving large voltages (20+ V). For more information about the THS3091 and THS3095 devices, see the data sheet, SLOS423. Both DAC outputs have optional transformer outputs to bypass the operational amplifiers, if needed. There are also options to bypass the onboard supplies to use higher external operational amplifier supplies. The amplifier circuits can be further optimized by following the guidelines in the application report, SBAA135. This optimization can be performed once the final filter and gain components have been selected. 4 Software Installation The enclosed CD-ROM contains all of the necessary software that is needed for the host personal computer (PC) to control the DAC5682Z and CDCM7005 on the TSW3070EVM.

Programming of the CDCM7005 and DAC5682Z is accomplished through this port. 6.4 Power Management The TSW3070 EVM requires an input of 6 VDC (refer to Section 8.2 for details). A current rating of at least 2 A is recommended for the 6-V supply. The rest of the supplies: 3.3, 1.8, ±5 V are all generated on the board with linear regulators. 7 Demonstration Kit Test Configuration Test Equipment 7.1 Test 7.1 Test Setup The test setup for the TSW3070EVM is shown in Figure 6. This setup shows the TSW3100 pattern generator supplying an LVDS signal to the TSW3070EVM (see the TSW3100 product folder, http://www.ti.com/tool/tsw3100evm). Figure 6. TSW3070EVM Driven by TSW3100 Pattern Generator 7.2 Test Equipment The following test equipment is required for testing the .TSW3070EVM. Some other equipment may be used; however, results may vary due to limitations of the instruments. • Power supply 6 VDC at 2 A • Spectrum Analyzer: Rhode & Schwarz FSU, FSQ, or equivalent • Pattern generator: TSW3100 using LVDS mode, or some other LVDS capable pattern generator • Oscilloscope: Probe clock and data lines for trouble shooting, measure voltage waveform in time domain • Digital voltmeter to verify signal levels 7.3 Calibration In order to measure the proper output power, the insertion loss of the analyzer cable must be calibrated. Measure a calibrated 0-dBm source to see how much loss is in the cable at the frequency of interest. 18 TSW3070EVM: Amplifier Interface to Current Sink DAC - Arbitrary Waveform Generator Demonstration Copyright © 2008–2016, Texas Instruments Incorporated SLWU055A – May 2008 – Revised May 2016 Submit Documentation Feedback Demonstration Kit Test Configuration Test Equipment 7.1 Test www.ti.com 7.4 Typical Performance Measurements The TSW3070EVM ac measurements at the transformer outputs can be used to verify the performance of the DAC5682Z if necessary, or if a reference signal is needed when measuring the performance at the OPA695, THS3091 or THS3095 output. The OPA695, THS3091 and THS3095 are both implemented in a differential-in to single-ended-out configuration. The gain of the OPA695 has been set to 2.2x, and the THS3091 and THS3095 have been set to a gain of 3.3x. The input on the OPA695 has an effective 25-Ω load on a 20-mA ac signal. The inputs of the THS3091 and THS3095 have an effective 50-Ω load with a 20-mA ac signal. Using the TSW3100 in the Multi-Tone GUI mode, a single tone can be generated and measured at both outputs. This measurement must be verified first before any other testing or modification of the board is attempted to ensure that all hardware and software interfaces are operational. The OPA695 output is about 1.8 Vpp, whereas the THS3095 is about 5 Vpp. Figure 7. Typical THS3091 and THS3095 Voltage Output, Default Gain 3.3x Figure 8. THS3091 and THS3095 With ±15-V External Supplies, 50-Ω Input, Gain at 10x SLWU055A – May 2008 – Revised May 2016 Submit Documentation Feedback TSW3070EVM: Amplifier Interface to Current Sink DAC - Arbitrary Waveform Generator Demonstration Copyright © 2008–2016, Texas Instruments Incorporated 19 Demonstration Kit Test Configuration Test Equipment 7.1 Test www.ti.com A low-pass filter (LPF) is between the DAC outputs and the OPA695, THS3091, and THS3095. This prevents any higher frequency DAC images from affecting performance of the amplifiers. The wide bandwidth OPA695 is typically operated at lower gains with smaller output swings with a wider input LPF, about 200 MHz. The THS3095 is normally operated at larger gains (larger feedback resistor) and larger output swings which results in narrower output bandwidth. Consequently, the LPF for the THS3091 and THS3095 is set lower at 100 MHz. Both LPFs are 50-Ω differential, fifth-order Chebyshev filters with a 0.1dB ripple.

This is useful information when programming the CDCM7005 to lock the DAC clock to the reference. Typically, the board is populated with an 800-MHz VCXO. 8.2 Engage Power Supplies 1. Connect the EVM supplied 18-AWG wires to the DC plug cable (Tensility 10-01776) to a qualified lab bench power supply. The 18-AWG red wire is the 6-V wire while the 18-AWG black wire is the ground wire. 2. Connect the 6-V power supply to J12, the Power In jack of the TSW3070 EVM. 3. Connect the PC USB port to J4 USB port of the TSW3070 EVM. 8.3 Verify Status of the Board The DAC software will detect if the USB port is active and if it is capable of reading the serial number from the EVM. This determines if the communication between the board and the PC is correct. The HOME menu of the DAC GUI software indicates this status. The VCXO and Reference LEDs (D1, D2) must be lit as well as the power LED (D18). 8.4 Program the CDCM7005 On the DAC5682z EVM GUI, click on Register Config which is located on the left side of the GUI. Program the registers as necessary manually or load a saved configuration file. An example file for loading the CDCM7005 called CDCM7005_4X_Interp.reg7005 can be found on the provided CD. To load this file, click on the Load Regs button on the lower center of the GUI. Navigate to the correct location, select this file, then click on OK. The default mode of GUI has the CDCM7005 Operation set to Buffer Mode. Click on this button and change the setting to PLL Mode. Next, change the VCXO Freq (MHz) default value of 983.04 to 800 by either clicking on the down arrow of this button or entering 800 manually. Hit enter and the new settings will be sent to the CDCM7005. Note that the CDCM7005 LOCK LED (D3) is now lit as it achieves lock between the VCXO and 10-MHz reference. This LED does not illuminate when using external VCXO. Figure 15.
