Hi Indeed, they are pretty amazing for a tiny little part. Ultimately physics does catch up with them. The resonator in the heart of the device has it’s limitations compared to a big chunk of quartz.
Things like ADEV or phase noise aren’t their strong suit when compared to a good OCXO. Note that the OCXO would be much larger and would probably pull a lot more power. It’s a good bet that the silicon gizmo will withstand a much harsher environment ( shock / vibe / acceleration …..) without there being much impact. How useful are they? It very much depends on what you are trying to do ….
