A Temperature Compensated Crystal Oscillator, abbreviated as TCXO, is a device that corrects the resonance frequency dependence based on the crystal temperature. The temperature compensated oscillator usually consists of a thermistor network, which generates a correction voltage to reduce frequency variations with temperature.
Temperature compensated crystal oscillators use temperature sensors to monitor the ambient temperature and compensate for the frequency of the crystal oscillator through a feedback loop. When the ambient temperature changes, the TCXO automatically adjusts the control voltage of the crystal oscillator to offset the frequency shift caused by temperature. This temperature compensation mechanism enables TCXOs to provide highly stable frequency output, suitable for various environments with temperature changes.
Communications
TCXOs are widely used in mobile communication base stations, satellite communication terminals, two-way radios, and other devices to ensure the accuracy and stability of data transmission.
Navigation Systems
TCXOs are used in Global Positioning Systems (GPS), Inertial Navigation Systems (INS), and other navigation equipment to provide precise time and frequency reference signals.
Radio Communications
TCXOs are used in radio frequency synthesizers, radio receivers, and transmitters to ensure the reliability and stability of wireless communication.
