Xtal osc module

[Dirk Bruere at NeoPax]

Can anyone recommend a xtal smt clock module for audio apps,
(12.288MHz), low jitter, 3V3?

What have you already rejected?

This one looks pretty good:http://www.conwin.com/datasheets/sm/sm111.pdf

Thanks.
My only thinking so far is that ADI DSP reference designs do not use
the best components, and the osc module for the ADC/DAC timing is
probably the most crucial part.

Have you established a spec on the maximum jitter you wish to allow?
It would probably be good to translate that to a phase noise spec,
since crystal oscillators are commonly spec'd for phase noise
performance. ADI has some decent ap info on the effects of jitter...
