Oscillators TCXO and VCTCXO

Typical application
Pilot circuit, Telecommunication

Features
TCXO - Temperature compensated crystal oscillator. Oscillator is most suitable for use when a small frequency tolerance is required in a wide temperature range.

Can be made in VCTCXO variant, ie a voltage-controlled crystal oscillator. This allows to change the oscillation frequency with external voltage.
