Q 26,0-JXS21-9-10/15-T1-FU-WA-LF Application Field and Working Principle

Q 26,0-JXS21-9-10/15-T1-FU-WA-LF, commonly known as a temperature-compensated crystal oscillator (TCXO), is a crystal oscillator that contains a circuit that compensates for the changes in the oscillation frequency due to temperature. It uses both its mechanical and electrical properties to maintain a constant frequency over a wide temperature range. TCXOs are commonly used in many modern electronics, including wireless communication, satellite navigation systems, industrial automation, and medical equipment.

In a TCXO, a crystal oscillator is designed to incorporate a temperature-compensated circuit for maintaining a constant oscillation frequency. This circuit consists of a voltage-controlled oscillator, an integrated circuit (IC) to store and read data, a reference voltage source, a thermistor, and a negative temperature coefficient (NTC) resistor. The voltage-controlled oscillator (VCO) is connected to the crystal oscillator and it is used to control the frequency of the oscillation. The IC stores and reads data that is used to adjust the VCO to provide the desired frequency. The reference voltage source provides a fixed voltage to the thermistor and the NTC resistor which are connected to the output of the TCXO. The thermistor and resistor help to maintain a constant temperature by countering the changes in oscillator frequency caused by temperature.

In addition to providing a constant oscillation frequency, TCXOs also offer improved accuracy and stability over traditional crystal oscillators. Their high frequency accuracy is typically better than one part per million (PPM). Their stability is also good and depends on the circuit design. Furthermore, the power consumption of TCXOs is much lower than that of other types of oscillators. This is due to the fact that the circuit design is able to minimize the power losses caused by the temperature-compensated circuitry.

TCXOs are used in various electronic applications such as wireless communication systems, satellite navigation systems and medical equipment. In wireless communication systems, TCXOs are used to prevent interference from frequency and amplitude offsets caused by temperature fluctuations. In satellite radio navigation systems, they enable highly accurate navigation capabilities by providing a stable frequency in the presence of varying temperatures. In medical equipment, they are used to monitor the vital signs of a patient and to maintain the accuracy of diagnostic tests over different environmental conditions.
