Working Principle

TB-19.440MDE-T oscillator has two main parts: the quartz crystal resonator and the electrical components such as capacitors, semiconductor packages and resistors. Operating frequency is generated from the quartz crystal resonator by the circuit of the electrical components. The quartz crystal resonator works in the same way as a tuning fork, which can vibrate at a certain frequency under the coupled electric field. When the external alternating voltage is applied to the quartz crystal resonator, it will vibrate and generate an oscillating signal which is determined by the frequency of the quartz crystal resonator. The electrical components serve to filter and amplify the output of the quartz crystal resonator, thus generating a stable frequency output which can be used in the circuit.

The frequency of the TB-19.440MDE-T oscillator can be adjusted by modifying the external elements of the circuit, such as the capacitor or resistor. The circuit can be designed based on the corresponding frequency to reach the highest accuracy of 0.2 ppm/°C. The frequency of the oscillator is relatively precise and can be guaranteed with a frequency control range of ±2%.
