Introduction to Oscillators

Oscillators are electronic circuits that generate a repeated regular signal. They are widely used in electronics and electrical engineering to generate signals of various frequencies. Oscillators can create signals that fluctuate between two different values or create repeated pulses with different frequencies. The frequency of the output signal is determined by the circuitry and its components.

There are many types of oscillators available. Commonly used oscillators include those based on RC networks, LC circuits, and crystal oscillators. These oscillators have different applications and vary in working principles. Some oscillators are used for signal generation in communication systems, while others are used in digital systems for the clock generation and waveform synthesis.

AOCJY-38.880MHZ-E-SW Application Field and Working Principle

The AOCJY-38.880MHZ-E-SW oscillator is a type of surface mount, ceramic resonator. It is designed to provide an output frequency of 38.880MHz with a typical frequency tolerance of ±20ppm. Additionally, it comes with high stability and good temperature performance. This oscillator has numerous applications in mobile telecommunication equipments and digital broadcasting systems.

The working principle of the AOCJY-38.880MHZ-E-SW oscillator is based on the combination of a quartz crystal and a nonlinear amplifier with negative resistance. A quartz crystal is a solid material composed of atoms arranged in an orderly and symmetrical way. It vibrates at a specific frequency when a voltage signal is applied across it. This frequency is determined by the size and shape of the crystal and its internal structure. The nonlinear amplifier is responsible for amplifying the vibration of the crystal and providing the oscillator with the necessary negative resistance to generate a sinusoidal output signal.

In this type of oscillator, a sinusoidal signal with an amplitude of 38.880MHz is generated by the feedback of the nonlinear amplifier. The output from this oscillator is a continuous sinusoidal signal of constant frequency, with no harmonic distortion.
