Hi--

This may be useful... 

The Microchip DM330011 dsPIC DSC starter kit appears to do just this ($60 at
Digikey).  

The Microchip website has a description:
   
<http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en534506>

And the user manual, which includes schematic:

And some sample software:
