Looking for stabilizer mezzanine with AD9910 (or similar) DDS

lriesebos

Hi all, reaching out to the community with a question.

I am aware of the stabilizer mezzanines listed here https://github.com/sinara-hw/Stabilizer/wiki#afe-mezzanines, but I was wondering if anyone is aware of a mezzanine with an AD9910 or similar DDS. Looking for amplitude control, sub-Hz frequency control, and the ability to provide a reference clock for the DDS.

Thanks!

You may be able to connect a Urukul on the Stabilizer's EEM port, though this hasn't been attempted before and there would be some development and perhaps hardware debugging involved.

sb10q interesting, I didn't think of that. A full Urukul board is a bit overkill, but would save the effort of making a PCB. Are you aware of any stabilizer projects or firmware that use the EEM port for such purposes? I did notice the pounder might be using the EEM for a QSPI connection.

Pounder meets the requirements you list and more.

rjo thanks for your reply. I have actually been thinking about that. Is has 4 less bits amplitude control, but that might be workable. Benefit is obviously that a lot of firmware is already available. Might give that a shot!
