Oscillators TCXO and VCTCXO

General application
Pilot circuit, telecommunications

Features
TCXO - Temperature Compensated Crystal Oscillator. The oscillator is the most suitable when a low frequency
tolerance is required in a wide temperature range.

VCTCXO variant (i.e. Voltage-Controlled Crystal Oscillator) can be produced as well. This variant enables the change in oscillation frequency with external voltage.
