Oscillators: 653E15935C3T Application Field and Working Principle

Oscillators are one of the main components found in electronic circuits. They are used to generate an electrical signal of a predetermined frequency and amplitude, such as radio-frequency (RF) oscillators used for wireless communication. The 653E15935C3T is a crystal oscillator, and a type of oscillator commonly used for timing and frequency control applications. This article will discuss the 653E15935C3T’s application field and working principle.

Application Field of 653E15935C3T

The 653E15935C3T is a temperature controlled crystal oscillator (TCXO). TCXOs are mainly used in timing applications, such as timing circuits that generate pulses of fixed frequency and duration. This crystal oscillator is especially popular for use in wireless radio technology, because its highly stable output allows transmission over long distances.

In addition to wireless radio technology, the 653E15935C3T is commonly used in other applications, such as GPS systems, cellular phones, Wi-Fi routers, satellite broadcasting, navigation systems, base stations, and telecom equipment.

Working Principle of 653E15935C3T

The 653E15935C3T crystal oscillator is a frequency- and temperature-controlled oscillator. Its frequency-control is typically set to between 25 and 50 millivolts (mV), while its temperature-control is usually set to between 0 and +50 degrees Celsius (+50°C). It operates on a quartz crystal, which vibrates in response to an alternating electrical current. This oscillation produces precise frequency- and temperature-controlled signals that are then used for timing accuracy.

The 653E15935C3T contains two parts: the oscillator circuit and the quartz crystal. The oscillator circuit is connected to the quartz crystal through an inductor-capacitor (LC) network, also known as an LC filter. This LC filter provides frequency- and temperature-control, which ensures that the TCXO can maintain a constant output over various temperatures. The quartz crystal is the main weather-resistant component of the oscillator, which is essential for maintaining frequency accuracy in various harsh environments. The combination of the two components results in extremely stable oscillations.

Conclusion

The 653E15935C3T is a crystal oscillator commonly used for timing and frequency control applications. This TCXO is mainly used in wireless radio technology, as its high stability output allows transmission over long distances. The working principle of the 653E15935C3T involves an oscillator circuit and a quartz crystal, with an LC filter providing frequency- and temperature-control. This combination of components yields highly stable oscillations suitable for timing accuracy.
