This user guide describes both the hardware and software setup needed to acquire data capture from AD9148-EBZ & AD9148-M5375-EBZ evaluation board to characterize AD9148 Quad 16-bit 1GSPS TxDAC+® digital-to-analog converter.

This guide shows how AD9148-EBZ & AD9148-M5375-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 DPG3 controller board.

Quick Start Guide

Reconfiguring the Evaluation Board

This section details the quick start procedures for setting up the AD9148-EBZ & AD9148-M5375-EBZ evaluation board. Refer to the section below to configure the power supply and the Reference & synchronization clock.

Power Supply Configuration

The evaluation board has a provision for on board or external power supply configuration.

Internal Power Supply

On board power supply is implemented by default. JP1 selects the supply voltage level for IOVDD. Refer to Figure 2.

  • When Pin 1 and Pin 2 are connected, IOVDD = 3.3 V (Default)
  • When Pin 2 and Pin 3 are connected, IOVDD = 1.8 V

    Figure 2. AD9148-EBZ JP1/AD9148-M5375-EBZ JP1

External Power Supply

To implement external supply configuration, remove the header shunt of six pin jumpers, as shown in Figure 3. Refer to Table 1 for external supply jumper connection.

Table 1. AD9148-EBZ/AD9148-M5375-EBZ Jumper Connection

Reference and Synchronization Clock

JP15 and JP18 selects the source for the reference and synchronization clock of the AD9148. the on board clocking is implemented by default. Refer to figure #4 to reconfigure the reference/ synchronization clock.

  • On board (from AD9516), center pads connected to inner pad.
  • Off board (External source), center pads connected to outer pad.

Evaluation Guide

  1. Follow Evaluation setup in Figure 1a and 1b.
    • Attach the evaluation board to SDP-H1 FMC connector using the AD-DAC-FMC-ADP adapter board.
    • Connect continuous wave generator for clock input to J1.
    • DAC output from J3 to a signal/spectrum analyzer.
    • Connect the evaluation board to PC via USB and to a 5V 1A power supply via banana plug cables.
    • Connect SDP-H1 to PC via USB and to a 12V 1A power supply.
    • Set clock input to 400MHz and 3dBm.
  2. Open the SPI software from Start > Programs > Analog Devices < 9148 > AD9148 SPI.
  3. With the default settings, click run. The update AD9516 should blink, refer to Figure 5.

    Figure 5. Running ACE Initial Configuration Wizard when using SDP-H1

  4. Open the DPGDownloader software from Start >Programs > Analog Devices > DPG > DPGDownloader. The DPG downloader should detect the AD9148 Evaluation board as well as the DCO Frequency.
  5. From DPGDownloader, Add Generator Waveforms pulldown menu select Single Tone and apply the settings as shown in Figure 6. Set the Data Rate to 100MHz and frequency to 15 MHz. Set DAC resolution to the DAC’s number of bits to 16. Check the “Generate Complex Data (I & Q)” box then uncheck the “Unsigned Data” box.
  6. Select the in-phase tone from the I Data Vector pulldown menu and the quadrature tone from the Q Data Vector pulldown menu.
