The working principle of TCXO 844002AGLF is based on a quartz crystal oscillator circuit containing an electromechanical quartz crystal vibrator. The crystal vibrator is an electrically excited crystal material, which produces oscillations at a frequency determined by the size and shape of the crystal itself. This frequency is usually tuned by adding or removing ceramic capacitors or inductors in the oscillator circuit. To compensate for temperature changes, a temperature sensor or thermistor can be included as part of the circuit. The sensor will detect changes in temperature and send a signal to the oscillator to adjust its frequency accordingly, thereby maintaining its stability.

The 844002AGLF contains an oscillator section and a temperature compensation circuit. The oscillator section is a free-running resonator circuit, containing a quartz crystal and associated resistor and capacitor components that determine the output frequency. The temperature compensation circuit consists of a temperature sensing element and an oscillator circuitry that are combined to automatically adjust the output frequency with temperature changes.

The 844002AGLF offers high precision and stability over a wide temperature range and is suitable for use in precision timing applications such as cable, telecommunications, wireless communication, instrumentation and test and measurement equipment. It provides a reliable, frequency-offset-free solution, ensuring long-term timing accuracy and stability.
