Subtag of oscillator

Anything about TCXOs, i.e. particular crystal oscillator circuits whose frequency stability vs. temperature is improved by using temperature-sensing devices (e.g. thermistors) to compensate temperature variations.

In a TCXO the temperature of the crystal is sensed and an appropriate compensation voltage is generated and applied to the crystal itself. That voltage counteracts the frequency variations due to temperature changes.

Q&A How to calculate the RC filter of a TCXO for a RFIC reference?

I have a 30MHz TCXO circuit (TCXO datasheet) like this serving as local oscillator to a RFIC: The RFIC manufacturer recommends to "add filtering caps" for high RF output cases. That is >20d...
