Hi I would say there are *very* few companies out there that will sell you high grade precision OCXO crystals in single piece quantities. I think you would get one much quicker and cheaper by pulling it out of an eBay OCXO. You can do good far removed phase noise with a lot of crystals. Once you look close in, the performance of the resonator matters. ADEV is the same issue, longer Tau’s are very resonator dependent.
