Oscillators

Oscillators are electronic circuits which generate a periodic signal, usually referred to as an oscillation, with an oscillating frequency. To generate the oscillation, a resonant circuit is used.

Within the oscillator family, crystal oscillators are widely used for timing, synchronization and frequency control in electronic devices. The SIT1602AC-31-18E-33.333330Y is a type of crystal oscillator which is designed to maintain a precise working frequency due to mechanical stability and excellent temperature characteristics.

Application Field

Due to its accuracy and temperature stability, the SIT1602AC-31-18E-33.333330Y crystal oscillator is well-suited for precision timing and synchronization applications. The applications the SIT1602AC-31-18E-33.333330Y crystal oscillator is typically used for include but not limited to radio and television receivers, telecommunication systems, professional instruments, frequency measurement systems, crystal filter circuits, military use, and high-precision time meters.

Working Principle

Essentially, a crystal oscillator is an electronic device used to generate a single, stable frequency. It works by passing an oscillating or alternating electrical current through a quartz crystal, which is a piezoelectric material, and using the periodic change in the crystal’s shape to produce an oscillating electrical signal. Quartz has a piezoelectric property, meaning it exhibits strain when it is subjected to an electric field. When an electric current is passed through a quartz crystal, it begins to expand and contract very rapidly at a specific frequency. This oscillation causes an oscillator circuit to produce an output signal that has a frequency that is dependent on the quartz crystal.

In the SIT1602AC-31-18E-33.333330Y crystal oscillator, the oscillator circuit includes an amplifier, a buffer, and a temperature compensator. The amplifier sets the basic oscillation frequency of the crystal oscillator circuit and is used to amplify the voltage of the quartz crystal so that it is large enough to be accurately measured by other circuit components. The buffer amplifies the signal from the quartz crystal before it is output to electronic devices within a system. It is often used to increase the impedance of the output signal and reduce interference. The temperature compensator helps to compensate for temperature variation in the crystal and oscillator circuit, as the frequency of the quartz crystal can be affected by changes in temperature.

Thus, the SIT1602AC-31-18E-33.333330Y crystal oscillator is a precision device that can generate a stable and accurate frequency. It is used in a wide range of applications where precise timing and synchronization functions are required.
