Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: Looking for serious reading material

Chase down the patents... I used to work with John Melanson before he went to Cirrus Logic. I think some of his patents might have the kind of detail you are interested in. I noticed that he has more than 100 of them, but looking for DDS and/or sigma delta might narrow them down.

When I tested them next to a high quality crystal they fared fairly well. I suspect that since their jitter error is fairly white that their errors aren't as audible as they might appear from the numbers. I'd use them in a lower cost DAC.
