The latest WaveVision software is available through the National Semiconductor website: http://www.national.com/analog/adc/wavevision5 1.0 Introduction This Evaluation Board may be used to evaluate the ADC16DV160. The ADC is a dual 16 bit analog to digital converters that provides data at rates of up to 160 MHz. 2.0 Board Assembly The evaluation board is designed to be used with the WaveVision5™ Data Capture Board which is connected to a personal computer through a USB port and running WaveVision5™ software, operating under Microsoft Windows. The software can perform an FFT on the captured data upon command and, in addition to a frequency domain plot, shows dynamic performance in U2 ADC16DV160 The ADC16DV160 Evaluation Board comes preassembled. Refer to the Bill of Materials in Section 8 for a description of components, to Figure 1 for major component placement and to Section 6 for the Evaluation Board schematic.

Refer to Figure 2 for the test set up. 4. The latest WaveVision software is available through the National Semiconductor website: http://www.national.com/analog/adc/wavevision5. If a software CD is included with the evaluation board kit, then use the provided software and instructions to install WaveVision and ensure compatibility with this evaluation board. 1. 2. 3. 5. Apply power to the WaveVision5™ board and connect it to the computer using a USB cable. See the WaveVision5™ User Guide for operation of that board. Connect the evaluation board to the WaveVision5™ Data Capture Board. NOTE: power to the WaveVision5 Data Capture Board should be applied before power to the ADC16DV160 Evaluation Board to insure that the FPGA on the WaveVision5 Data Capture Board is not damaged. Connect a clean +3.0V power supply to Power Connectors P1 and P4. Connect a clean +1.8V power supply to Power Connectors P2 and P3. Connect a 160 MHz signal from a 50-Ohm source to connector J4 for the input Clock. Be sure to use a bandpass filter before the Evaluation Board. Set the amplitude to 18 dBm. Connect a signal from a 50-Ohm source to connector J2 (I Channel) or J3 (Q-Channel). Be sure to use a bandpass filter before the Evaluation Board. For best results, also attach a 3dB 50 ohm attenuator right at the input SMA of the eval board. This will help match the impedance between the cables/signal source to the eval board input. Adjust the input signal amplitude as needed to ensure that the signal does not over-range by examinining a histogram of the output data with the WaveVision™ software. 4.0 Functional Description The ADC16DV160 Evaluation Board schematic is shown in Section 6. A list of test points and jumper settings can be found in the Appendix. 4.1 Analog Input To obtain the best distortion results the analog input network must be optimized for the signal frequency being applied. The ADC16DV160 Evaluation Board comes configured for input frequencies greater than 70MHz. To accurately evaluate the dynamic performance of this converter, the input test signal will have to be passed through a high-quality bandpass filter. 4.2 ADC reference circuitry 4 http://www.national.com This Evaluation Board is configured to use the internal reference. 4.3 ADC clock circuit Care must be taken to provide a high quality low jitter clock source. The board is configured to accept a single ended sinusoidal. It converts the sine wave to a differential signal through transformer T4. Refer to the schematic for more detail. 4.4 Power Supply Connections Power is applied to the board through power connectors P1 – P4. Care must be taken to observe the correct polarity. 5.0 Installing the ADC16DV160 Evaluation Board The evaluation board requires a dual power supplies as described in Section 4.4. NOTE: power to the WaveVision5 Data Capture Board should be applied before power to the ADC16DV160 Evaluation Board to insure that the FPGA on the WaveVision5 Data Capture Board is not damaged. A low noise sinusoidal signal source should be connected to the Clock Input SMA connector J4. An appropriate signal source should be connected to the Signal Input SMA connector J2. When evaluating dynamic performance, an appropriate signal generator (such as R&S SMA-100A) with 50 Ohm source impedance should be connected to the Analog Input connector through an appropriate bandpass filter as even the best signal generator available can not produce a signal pure enough to evaluate the dynamic performance of an ADC. If this board is used in conjunction with the the WaveVision5™ Data Capture Board and WaveVision5™ software, a USB cable must be connected between the Data Capture Board and the host. See the WaveVision5™ Data Capture Board manual for details. 5 http://www.national.com 6.0 Hardware Schematic 1 VAD3.0 1 1 SDA SCL VCC VDR1.8 C3 0.1u 2 2 2 R21 10 1 2 24 23 22 21 20 19 18 17 16 15 14

Reproduction 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. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
