EVALUATING THE AD9704/AD9705/AD9706/AD9707 DIGITAL-TO-ANALOG CONVERTER
Preface
This user guide describes both the hardware and software setup needed to acquire data capture from AD9704-DPG2-EBZ/AD9705-DPG2-EBZ/AD9706-DPG2-EBZ/AD9707-DPG2-EBZ evaluation board to characterize AD9704/AD9705/AD9706/AD9707 8-/10-/12-/14-bit 175Msps high-speed digital-to-analog converter.
This guide shows how AD970x-DPG2-EBZ works with SDP-H1 controller board developed by Analog Devices. Link to the previous user guide document is provided for customers who still have the DPG2 or DPG3 controller board.

Helpful Files:
- Quick Start Guide for DPG2/DPG3 users
Software Needed:
- DPG Lite (Recommended; Installed with ACE) or DPG Downloader
Known Issue: ACE may fail to detect HS-DAC boards, details here.
Hardware Needed:
- SDP-H1 (EVAL-SDP-CH1Z) Board
- 12Vdc 1A Wall Adapter for SDP-H1
- AD-DAC-FMC-ADP High-Speed DAC Evaluation Board to FMC Adaptor Board
- PC with ACE and DPG Lite Software Applications
- High-Frequency Continuous Wave Generator
- Signal/Spectrum Analyzer
- (2) USB A to USB Mini Cables
- (2) SMA Cables
Quick Start Guide
- Attach AD9704-DPG2-EBZ/AD9705-DPG2-EBZ/AD9706-DPG2-EBZ/AD9707-DPG2-EBZ to SDP-H1 FMC connector using the AD-DAC-FMC-ADP adapter board. Connect continuous wave generator for clock input to J10 and DAC output from S4 to a signal/spectrum analyzer. Connect the evaluation board to PC via USB. Refer to Figure 1.
- Connect SDP-H1 to PC via USB and to a 12Vdc 1A power supply.
- Set clock input to 175MHz and 3dBm.
- Press SW1 Button to reset the AD9704/AD9705/AD9706/AD9707.
- Open ACE. The board will be automatically recognized by the software. Otherwise, install the plugin for AD9704/05/06/07 evaluation board.
- In ACE, apply the default values in the Initial Configuration wizard as shown in Figure 2.
Figure 2. ACE Initial Configuration Wizard for EVAL-AD9707
- Start DPG Lite or DPG Downloader. At the SDP-H1 part of the software, the device part number and data clock frequency of 175MHz should be displayed.
- In DPG Lite or DPG Downloader, from the “Add Generator Waveforms” pulldown menu select “Single Tone” and apply the settings as shown in Figure 3. Set data rate to 175MHz and desired frequency to 20MHz. Set DAC resolution to the DAC’s number of bits (14 for AD9707, 12 for AD9706, and so on). Check off the “Unsigned Data” box.

- Select the tone from the “Data Vector” pulldown menu.
- Press the download arrow and then the play button. The FFT similar to Figure 4 should appear in the signal/spectrum analyzer.
