LFSPXO025492REEL application field and working principle

LFSPXO025492REEL is a high-performance temperature-compensated Crystal Oscillator (TXCO) that provides ultra-low phase noise and ultra-high stability. It is available in the frequency range from 10MHz to 1GHz and can be customized to satisfy specific requirements. This oscillator is widely used in communications, military, medical, instrumentation, automotive and aerospace applications.

A typical temperature-compensated crystal oscillator consists mainly of an oscillator circuit, an temperature sensor, and an active temperature compensation circuit. The oscillator circuit usually consists of a low-noise transistor, a resonator such as crystal or ceramic resonator, and some passive parts. The temperature sensor senses the ambient temperature and generates an analog voltage proportional to the temperature. The temperature compensation circuit amplifies the output of the temperature sensor and then, according to this amplified voltage, adjusts the oscillator frequency to keep it within an acceptable range. In this way, the oscillator frequency is maintained with high accuracy for extreme temperatures.

The oscillator operation of LFSPXO025492REEL can be summarized as follows. The oscillator circuit produces an output signal at its specified frequency. This output signal passes through a temperature sensor and then enters the active temperature compensation circuit. The temperature compensation circuit adjusts the oscillation frequency of the oscillator according to the ambient temperature, keeping the oscillation frequency stable. At the same time, the oscillator circuit also has low phase noise and low jitter performance, ensuring that the signal output from the oscillator is of better quality.

The advantages of LFSPXO025492REEL can be summarized as the following points. First, this product has high stability over temperature and long-term aging.
