Hi,
Apologies for the late response.
I am not sure about your plan. Can you send a block diagram? My assumption is it looks like the AD2S80 Application note AN-265. Please refer to the link. http://www.analog.com/static/imported-files/application_notes/5033918389419AN-265.pdf. This is the most similar idea that I can imagine.
There are other Application Notes from the AD2S80 webpage. You may refer to these documents on this link.
Regards,
Jonathan
