Hello Krisi,

Not SiC but SOI based. Plus internal confidential recipes of course.

Thank you very much for the invitation, I will transfer it internally.

thank you @X_REL Emmanuel...250C operation sounds very impressive, is this silicon or other semiconductor like silicon carbide...would you be interested in giving a talk on this topic at emerging technologies conference in Grenoble in 2014? details at www.cmosetr.com, if so pls email me at kris.iniewski@gmail.com

Hello Krisi,

High temperature electonics is our expertise, and it may be surprising to you but X-REL Semiconductor is doing circuits which are stable up to 250°C and more for some references! You should check our website: www.x-relsemi.com. High temperature electronics is progressing very quickly and is becoming a reality!

I don't think friction is as much of a concern as ambient temperature. Friction could affect local ambient temperature but your clock would drift from other temperature variations as well.

Temperature is the real killer of oscillator stability, which is why TCXO uses a little heater to maintain a constant internal temperature. SiTimes' main purpose here is to convince the engineering community that MEMS oscillators don't just server the low-end of timing apps, but will eventually serve the whole spectrum of users. SiTime would not tell me there trade secrets, but others have achieve high temp stability by building resonators with two different materials with opposite temperature coefficients that cancel out the effects on frequency of changes in temp.

Krisi: I'm extrapolating and oversimplifying a bit here, but temperature reflects "friction," so a steady temperature suggests greater efficiency, which I would hope would result in lower power consumption and faster computation.  I may be jumpging to several conclusions there, but I'm trying to understand this.

Can anyone improve on my explanation, please?

Very impressive indeed...but I wonder what is teh point of such a stellar temperature stability...everything else in physics moves with the temperature so one temperature stable point doesn't solve much

I'm not saying this is wrong -- it's remarkable, and I hope it's true. But I'm wary of claims made by a company about itself. Is there an outside verifying source on this?
