We know what a OCXO is and a TCXO is. I was at a presentation at work a
whike back and they called what you describe a "MPCXO" or MicroProcessor
Compensated XO. They said the characteristics were between the OCXO and
TCXO
Doesn't the thunderbolt do this. I think it watches the aging rate of the
OCXO and adjusts during hold over.
