Hi,

 

I have development board of AD9117 Dual Low Power 14-bit DAC, connected with

AD-DAC-FMC-ADP to Spartan 6 LX150T Development board. I have made simple

project with DDS sine and cosine output for go on Eval-ADRF6755SDZ.

 

Use the "Analog Output" for LO cancellation with DAC normal working (I/Q output).

 

The datasheet is not clear on this part. How use AUX I and AUX Q with DAC normal

working (output signal). I want use a connection scheme on Page 49 Figure 108, but

I see two DAC.

 

How use only one AD9117 (I/Q output) with cancellation of local oscillator ?

 

Thanks very much.

 

Gabriele.
