If the AD9747 evaluation board has been recognized by the PC, “AD9747 RevB” should be populated in the Evaluation Board 
field in the Hardware Config panel.   

-

 

Generate a sinewave by pulling down the “Add Generated Waveform” menu and choosing “Single Tone”.  Fill in the form as 
shown in Figure 3 (Sample Rate = 100MHz, Desired Frequency = 17.0MHz, etc.).  Select the I and Q data vectors in the data 
selection panel. 

-

 

Configure the eval board by writing the value 01 to register 1E1.  This configures the AD9516 to use the CLK input to drive the 
clock path. 

 

 

-

 

Bypass the clock dividers on the AD9516. 

 

-

 

The DCO frequency field in the DPGDownloader window should now be reading something close to 100MHz.   

-

 

Next hit the download 

 button.  This transfers the data from the PC to the DPG memory. 

-

 

When the vector has finished downloading, hit the play 

button.  This starts the DPG2 transmitting data to the eval board. 

-

 

The output from J5 and J9 should be a clean 29MHz tone as shown below:
