Hello. I am a new learner on AD9914 evaluation board, now I have some troubles to get the board work. I noticed that the user guide said,
Connect a high frequency input clock signal up to 3.5/2.5 GHz to J104. or
Connect a lower input reference frequency to J104 and enable the internal clock multiplier (PLL).
What kind of signal will I use to drive the board, the wave form, frequency, amplitude and the phase, and can I use a signal source or a signal generator to provide the input REF_CLK signal?
Furthemore, if I want to use the board to produce a 3.5GHz signal, which mode should I choose, and what kind of input REF_CLK signal should I use with the features mentioned above?
Looking forward for your reply.
Wish you a happy Christmas!
