Oscillators

Oscillators are specialized components used to generate a periodic signal, or repetitive waveform. The CE3390–20.000 oscillator is a crystal controlled oscillator capable of generating stable frequency outputs, which makes it suitable for applications such as timing and control.

Application Field

The CE3390–20.000 has diverse applications in consumer electronic devices, sonar, medical devices, test equipment, and aerospace industry. It is also used in cellular phones, tablets, camcorders, personal computers, portable media players, game systems, as well as portable stations and other tactical wireless products.

The CE3390–20.000 is commonly used for communication systems like RF transceivers, radio modems, satellite receivers, wireless LAN, and digital satellite TV as it has the capability to transmit or receive data accurately. The component is used mainly for wireless communication, as wireless systems depend on regular and precise signal transmissions.

Working Principle

The CE3390–20.000 oscillator usually consists of a quartz crystal, a tuning capacitor, and an op-amp, or an equivalent of that combination, all of which function together for the oscillation process.

The crystal is the key component in the oscillator as it is highly precise and has a defined frequency, which depends primarily on the physical dimensions of the crystal itself. A tuning capacitor is used in combination with the crystal to adjust the frequency of the desired output. The op-amp is the part of the oscillator that amplifies the signal.

The process starts with the fixed frequency of the crystal, which is then modified by the tuning capacitor. The resulting frequency is amplified by the op-amp until it reaches the desired level, which is then fed back into the circuit in a feedback loop. This feedback loop results in oscillation at a specific frequency, which is the desired output from the oscillator.

Conclusion

The CE3390–20.000 oscillator is a stable crystal controlled oscillator capable of generating various frequency outputs for various applications. It is used in many consumer electronic devices such as cellular phones, tablets, camcorders, personal computers, portable media players, game systems, as well as portable stations and other tactical wireless products for communication systems. The oscillator typically consists of a quartz crystal, a tuning capacitor, and an op-amp, which work together to produce a specific frequency of output.
