EVALUATING THE AD9736/AD9735/AD9734 DIGITAL-TO-ANALOG CONVERTER

Preface

This user guide describes both the hardware and software setup needed to acquire data capture from AD9736-DPG2-EBZ evaluation board to characterize AD9736 14-bit 1200 MSPS digital-to-analog converter.

This guide shows how AD9736-DPG2-EBZ works with SDP-H1 or ADS7-V2 controller board developed by Analog Devices. Documentation and software updates for using the AD9734/AD9735/AD9736 Evaluation Boards are included in a self-extracting update file. Documentation can also be downloaded individually below.

Known Issue: ACE may fail to detect HS-DAC boards, details here.

Hardware Needed:

  • AD9736-DPG2-EBZ Evaluation Board
  • SDP-H1 (EVAL-SDP-CH1Z) or ADS7-V2EBZ Evaluation Kit
  • AD-DAC-FMC-ADP High-Speed DAC Evaluation Board to FMC Adaptor Board
  • 5Vdc 2A Power Supply
  • PC with ACE and DPG Lite Software Applications
  • 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 2.5A Wall Wart
    • USB-A to USB-Mini Cable
  • The following are included in ADS7-V2 Evaluation Kit:
    • 12V 60W AC/DC Power Supply
    • Power Cord
    • USB-A to USB-B Cable

Quick Start Guide

  1. Attach the evaluation board to the FMC connector of SDP-H1 or ADS7-V2 using the AD-DAC-FMC-ADP adapter board. Connect continuous wave generator for clock input to J1, and the DAC output from J2 to a signal/spectrum analyzer. Connect the evaluation board to PC via USB and to a 5Vdc 2A power supply via banana plug cables. Refer to Figures 1a and 1b.Set clock input to 500 MHz and 6 dBm.
    • If using SDP-H1, Connect to PC via USB and to a 12Vdc wall wart.
    • If using ADS7-V2, Connect to PC via USB and to a 12V 60W AC/DC power supply. Switch the board ON using S1 beside the connector for 12V supply.
  2. Open ACE. The board will automatically be recognized by the software. Otherwise, install the plugin for AD9736 evaluation board. Apply the configuration wizard settings shown in Figure 2.

  3. Start DPG Lite or DPG Downloader. At the SDP-H1 or ADS7-V2 settings, ensure that Evaluation board is equal to AD9736 and DCO frequency of around 250 MHz should be displayed.
  4. In DPG Lite or DPG Downloader, from the Add Generator Waveforms pulldown menu, select Single Tone and apply the settings as shown in Figures 3a and 3b.Set Data Rate to 500 MHz and Desired Frequency to 50 MHz.
  5. Continuing on setting up DPG Lite or DPG Downloader, set DAC resolution to 14 bits.

  6. Select the Single tone from the Data Vector pulldown menu
  7. Press the download arrow and then the play button. The FFT plots similar to Figures 4 should appear in the signal/spectrum analyzer.

Troubleshooting

This section lists items to check and practices to use when debugging any unexpected performance of a board. If unexpected results occur:

  • Check the supply voltage of the evaluation board. Voltage rail should be 3.3V.
  • Check if all (3) blue LEDs on the AD-DAC-FMC-ADP board is lit up. Reconnect the board to the FMC connector of SDP-H1 if not lit up.
  • Check if the SDP-H1 is being supplied properly by 12Vdc adaptor. Some LEDs on the SDP-H1 should lit up.
  • Power cycle both the SDP-H1/ADS7-V2 and the AD9736 evaluation board.
  • Check on the Spectrum Analyzer if the DAC clock inputs are properly driven. For 500MHz clock, the spectrum analyzer should detect a weak signal at 500MHz. If not detected, check properly the clock source and connections.
  • Disconnect and reconnect the SDP-H1 /ADS7-V2 and AD9736 evaluation board. Reopen DPG Lite software.
