mmmmmh , it sound hard to built. But someone has made it. The Expensive, very performant, OCXO are perhaps the lowest phase noise oscillators ( even that Rb O).
In my knowledge, the keywords are:
- SC cut rather than AT cut
- excellent thermostatic oven and large time time constant (big mass)
- low noise circuitry
- dynamic range as large as possible
- excellent vibration mitigation
okay let complicate
I considering to built it internal (in to the IC 130nm)
Maybe i am wrong, I am looking for very low jitter (cycle to cycle) low than 100psec
Check the low noise crystall oscilator proposed by dr. Ulrich Rhode in the '70. The output is taken from a small resistor (10-22Ohm) connected in series with the crystall., and the amplified.
Since the requirement is @10kHz and fixed frequency maybe you can add a sharp crystal filter at the output to reduce the noise.
