Hello, Jim,
I suppose that one of the alternatives that you've explored are the
ABLNO from Abracon http://www.abracon.com/Precisiontiming/ABLNO.pdf
They say that they are 3rd overtone, but it seems more an AT-cut than a
SC, and anyway is around 10dB poorer than your requirements. An I
suppose that to make surgery in an AOCJY (that fully meets your
requirement) to remove the oven will not be adequate :) Also it is a bit
bulky...
Regards,
Javier

For a project at work, I'm looking for a good close in phase noise
oscillator (better than -100dBc@ 10Hz, -120dBc would be nice) at 100
MHz in a SMT form factor. But it doesn't need good temperature
stability. There's tons of SMT OCXOs out there with reasonably good
performance, but they draw "watts". My application is actually quite
temperature stable already AND I have an external reference to measure
against.
Most of the lower powered oscillator modules are TCXO, and have,
maybe, -80dBc at 10MHz.
I guess we could go to a discrete design with a crystal and amplifier,
but a little clock module would be a simpler solution.
