AD9914 in an RF SSB modulation setup

I am currently working on a project in the field of superconducting quantum electrodynamics that requires the use of an AD9914 direct digital synthesizer. The DDS will be the intermediate frequency signal for an RF SSB modulation setup using an IQ mixer. I have a few questions regarding the DDS:



- I would like to use a 10 MHz sinusoidal wave atomic clock as the reference clock for the DDS. Is there a recommended architecture for this? Would such a clock work well with the AD9914?


- What are the recommended specifications for the DC power supply (in terms of stability, noise, etc.) for the DDS in the setup described above?

Thank you,
