I would be interested to hear if you have had any success with your approach. I too have found the out-of-the-box solution provided by AD to be a bit more than what I really need. My initial application involves sending relatively low sample rate data through the DAC and periodically grabbing snapshots from the ADC... also at a relatively low sample rate. In the future, we could be using more of the capabilities of AD's devices (probably using the XCOMMS2 board). For now though I'm trying to do this on a shoestring budget with the Zedboard. So like you, I found not much room left for my own stuff once I have the reference design in place. My gut feel - and I've only been looking at this for a day or two at this point - is that I could gen up my own simplified DAC and ADC interfaces running at the lower sample rates. This I hope will yield a smaller more compact design. For instance, I won't need all the extra baggage for dealing with interlaced data going into a 500 MHz LVDS link to the DAC. Any tips you or the AD folks might have would be greatly appreciated.
