Oh, you were looking for 1E-12.. I was thinking 1E-9 would be good enough.

The other issue is that the phase noise might be pretty bad with a cheap 
crystal, if it's not particularly high Q.   Probably not what you want 
to use if you're multiplying it up for the carrier on your 240GHz 
narrowband transmitter.
