Re: oscillator design with a long xtal lead

Hello Tim,


You can encapsulate the oscillator and connect the crystal via glass-insulated terminals if needed. Encapsulation is quite common for medical implants where for obvious reasons outgassing would not be cool.

I suspect that the level of outgassing that would be absolutely unacceptable for a high-vacuum application would be orders of magnitude below the radar screen in many medical applications -- particularly if the gas involved was biologically benign, like oxygen, water or hydrogen.


True. But then I wonder how he is going to get a cable or connector in there that won't be outgassing.
