Hello,

 

I am planning to use AD9951 in DDS which cover from audio frequencies up to RF ( ~ 100MHz). In all applications I saw that output of DDS is connected to trifilar transformer and then is low-pass filter.

 

I would like to use just pull-up resistors on complementary outputs and then low-pass. It there any drawback of this connection? Or, another possibility is to use AD8021 and then low-pass.

 

What can you recommend me ?

 

Thank you in advance,

vaclav
