Here is a typical oscillator's datasheet:
http://pdf1.alldatasheet.com/datasheet-pdf/view/161044/EPSON/SG-8002DB.html

It is programmable in 0.1 KC steps up to 125 MC.

True, and that may or may not be a problem depending on the 
circuits following.  If it is, a low-pass filter at a 5 volt signal level
should be easy.   I'm going to get moving on this one, I think.
