I would like to ask , I would like to use #AD9954 evaluation board output a simple single frequency clock (after comparator), how do I set the software parameters. At present only DUT1, external clock how to give?
You can view a programming example of the part in page 33 of the datasheet. This sequence is a good guide for single tone generation. The guide is comprehensive enough that you can mimic the sequence using the evaluation software.
IOUT has already a connection going to COMP_IN of the board, You just need to populate R4 and R5 with 0 ohm resistors if they are not yet attached.
On your last sentence - I'm sorry but I didn't get the question, I'd like to ask to restate your question again. Thank you.
