In DDS AD9858 datasheet, it is possible to use a transformer at the DDS output pins, i.e. Iout and --Iout.
1. What is the benefits using a transformer at the DDS output?
2. I want to convert diff output to single end output, so I think to using Configuration A transformer, using secondary linking to the DDS diff output, and using primary for single end output. Is it right?
3. My single end output impedance is 50R, so the impedance ratio of the transformer should be "1:1", right?
Thank you very much.
