I think you will get bonus points if your design can accept an external 10MHz reference provided by a GPS-disciplined oscillator. If there was some convenient way to adjust out the crystal aging for use when the external reference isn't available, that would be even better. I've been thinking of designing something along these lines, but I won't complain if you do the hard work and I can just buy one from you. ;) -- Mark J.
