Hello All,
I thought this may be of interest to the group - a start-up company - Sand9
- has developed a temperature controlled MEMS oscillator (TCMO):

I see nothing very special about this MEMS compared to others I've seen.
Phase-noise measure stops at 12 kHz, which is not too hard, as the
cut-over to CMOS oscillator is below that in the step-up PLL.
MEMS might be good for certain tasks, but for closer in noise I've only
seen some progress recently, but not measured it myself. Close-in noise
seems to have been pretty bad for all MEMS so far.
Cheers,
Magnus
