Is it possible to set AD9959 eval board generate lower frequencies

Hello,

 

I need to generate frequencies with a range 100Hz - 2MHz using AD9959 eval board. The specs says the min frequency is 1MHz. Nevertheless in one of the previous discussions it was said that it was transformer who sets this limit and that DDS can actually generate all range of frequencies.

 

Question is: What modifications to the eval board shall I do to get out the lower frequencies? (Desoldering transformer and populating the resistor instead etc.?)

 

I am interested in making the least modifications possible to the board.

 

Many thanks in advance,

 

Reni
