EVALUATING THE AD9139 DIGITAL-TO-ANALOG CONVERTER

Preface

This user guide describes both the hardware and software setup needed to acquire data capture from AD9139-EBZ evaluation board to characterize AD9139 16-bit, 1.6GSPS, TxDAC+® digital-to-analog converter. This guide shows how ADS7-V2EBZ / SDP-H1 controller board automatically formats the data and sends it to the AD9139-EBZ developed by Analog Devices. Link to the previous user guide document is provided for customers who still have the DPG3 controller board.

  • AD-DAC-FMC-ADP High-Speed DAC Evaluation Board to FMC Adaptor Board
  • PC with ACE and DPG Lite Software Applications
  • 5Vdc Power Supply
  • (2) Banana Plug Cables
  • High-Frequency Continuous Wave Generator
  • Signal/Spectrum Analyzer
  • USB-A to USB-Mini Cable
  • (2) SMA Cables
  • The following are included in SDP-H1 Evaluation Kit:
    • 12Vdc Wall Adapter
    • USB-A to USB-Mini Cable
  • The following are included in ADS7-V2 Evaluation Kit:
    • 12Vdc Power Supply
    • Power Cord
    • USB-A to USB-B Cable

Quick Start Guide

  1. Follow evaluation setup in Figure 1a and 1b.
    • Attach the AD9139-EBZ evaluation board to ADS7-V2EBZ/SDP-H1 connector using the AD-DAC-FMC-ADP adapter board.
    • Connect continuous wave generator for clock input to J1 (AD9516_CLKIN).
    • Connect output from J3 (DAC1 output) to a signal/spectrum analyzer.
    • Connect the evaluation board to PC via USB and to a 5Vdc power supply via banana plug cables.
    • Connect ADS7-V2EBZ/SDP-H1 to PC via USB and to a 12Vdc power supply.
    • Set clock input to 500MHz and 0dBm.
  2. Open ACE. The board will automatically be recognized by the software. Otherwise, install the plugin for AD9139 evaluation board. Double click this board then modify the configuration, refer to figure 2.:
    • If ADS7-V2EBZ is used, set interpolation to 2.
    • If SDP-H1 is used, set interpolation to 1.

  3. Open DPGDownloaderLite. The evaluation board, controller board and DCO Frequency will be automatically recognized by DPG.
    • If ADS7-V2EBZ is used, a DCO Frequency of around 125 MHz should be displayed.
    • If SDPH1 is used, a DCO Frequency of around 250 MHz should be displayed.
  4. In DPGDownloaderLite, from the Add Generator Waveforms pulldown menu, select Single Tone and apply the settings as shown in Figures 3a and 3b. The data rate in DPG software should be equal to the data rate in ACE.
    • If ADS7-V2EBZ is used, set Data Rate to 250 MHz and Desired Frequency to 22 MHz.
    • If SDPH1 is used, set Data Rate to 500 MHz and Desired Frequency to 22 MHz.
  5. Continuing on setting up DPGDownloaderLite, set DAC Resolution to 16 bits. Uncheck the Generate Complex Data (I & Q) box and Unsigned Data box.
  6. Select the in-phase tone from the I Data Vector pulldown menu.
