INTRODUCTION 

The AD9747 Evaluation Board connects to the Analog Devices Digital Pattern Generator (DPG2) to allow for quick evaluation of the 
AD9747.  The DPG2 allows the user to create many types of digital vectors and transmit these at speed to the AD9747 in any of the 
AD9747 operating modes.  The AD9747 evaluation board is configured over USB from a panel within the DPGDownloader software. 

(Note: The AD9747 operation is described in detail.  The operation of the other devices in the family is described in a later section.) 

SOFTWARE INSTALLATION 

The AD9747 application software, DPGDownloader, should be installed on the PC prior connecting the hardware to the PC. The DAC 
Software Suite is included on the Evaluation Board CD, or can be downloaded from the DPG web site at 

http://www.analog.com/dpg

This will install DPGDownloader required for loading vectors into the DPG2 and configuring the AD9747 evaluation board. 

HARDWARE SETUP (DAC OUTPUT) 

Once the DPGDownloader software is installed, the hardware can be connected as shown in Figure 1.   A single 5V power supply powers 
the evaluation board. The power supply should be able to source up to 1A to cover all of the board’s operating conditions.  A low jitter 
clock source (< 0.5psec RMS) should be used for the DACCLK.  A sinusoidal clock output level of 0 to 4dBm is optimal.  By default, the 
DAC outputs are connected to SMA connectors for evaluation.  Both DAC outputs are available.  Later in document, the modifications 
for observing the modulator output and different clocking options will be shown. The evaluation board plugs directly into the DPG2.  
The PC connects to both the DPG2 and the evaluation board through USB cables.
