The key idea is to have an external clock input.  I don't think the frequency 
is critical for our usage.

All the audio chips I've looked at have a DSP filter that scales with the 
clock frequency.  I'd expect them to work as long as the clock isn't too 
fast.  You will just get a strange sampling rate.

The analog front end has a rough anti-aliasing filter.  You might get 
troubles if the clock is too slow and the input signal has energy in the band 
that gets aliased down on top of the signal.
