637V15625C2T Working Principle

The 637V15625C2T oscillator is a transistor-controlled high-precision oscillator that generates a stable sine wave output. The output frequency of the 637V15625C2T oscillator is determined by the reference frequency of the quartz crystals, which is in turn influenced by the parallel capacitance of the oscillator circuit. When the power is turned on, the voltage applied to the quartz crystal causes it to vibrate at its resonant frequency. This frequency is then fed to the base of a transistor, where the signal is amplified and sent to the output of the oscillator. The amplitude of the output signal is controlled by another variable capacitor in the oscillator circuit.

The frequency accuracy of the 637V15625C2T oscillator is very high, typically 0.002-0.003% over a temperature range of -5 to 55°C. This accuracy is achieved by using a quartz crystal that is specifically designed to provide high accuracy at a given frequency. Moreover, the circuit also includes a temperature compensating capacitor which compensates the frequency drift over a wide temperature range. The frequency stability of the 637V15625C2T oscillator is also good, with an aging rate of less than 0.1 ppm per year.

In conclusion, the 637V15625C2T oscillator is a highly stable, precision oscillator whose application field spans several industries. It has an extremely high frequency accuracy and excellent frequency stability, making it a popular choice for precision timing and frequency applications.
