Oscillators

590BB133M000DGR Application Field and Working Principle

Oscillators are electronic circuits that generate a continuous, periodic signal without any external input. The standard 590BB133M000DGR oscillators from WES Components are specially designed for use as clock oscillators and are used widely in devices such as computers, radio, television, and test equipment. This oscillator has a wide frequency range of 1kHz to 13.3MHz with an operating temperature of -55°C to +125°C.

Application Field

The 590BB133M000DGR oscillator is used mainly as a clock generator in a variety of electronic devices used for timing and synchronization, such as computers, cellular phones, automotive control systems, audio amplifiers, etc. In computer systems, for example, the clock oscillator facilitates the running of programs accurately and efficiently. In communication systems, the oscillator is used to tune and stabilize the frequency of the signal, so that it can be detected at the receiving end. The 590BB133M000DGR oscillator is also used to provide the reference clock necessary for many types of digital signal processing equipment.

Working Principle

Generally speaking, an oscillator is a circuit that produces an output signal without requiring an input signal. The oscillator is an active circuit, typically depending on the positive feedback of its components. In a clock oscillator, the most important component is an amplifier, which is connected to two feedback circuits. The amplifier amplifies the output signal and feeds it back to the input. The two feedback circuits control the amplification of the signal and restrict the oscillation frequency to a specific range of frequencies. The two feedback circuits consist of a tank circuit and a capacitor. The tank circuit is made up of one or more inductors and one or more capacitors. The tank circuit limits the frequency of the oscillator and enables it to generate a single frequency or a range of predetermined frequencies. The capacitor also affects the frequency of the oscillator, but it also affects the gain.

In the 590BB133M000DGR oscillator, the amplifier is a Schottky diode, which is connected in parallel to the two ceramic resonators. The ceramic resonators also function as the feedback circuits for the oscillator. The Schottky diode is two diodes connected in series, which enable the oscillator to maintain a constant output amplitude over the entire frequency range. The output voltage of the 590BB133M000DGR oscillator is regulated by a voltage regulator, which also ensures the oscillator’s low current consumption and accurate frequency than other types of oscillators.

Conclusion

The 590BB133M000DGR oscillator from WES Components is a widely used oscillator, designed specifically for use as a clock oscillator. It is used in a wide range of devices due to its wide range of frequencies from 1kHz to 13.3MHz. Its low current consumption and accurate frequency also make it a reliable choice for many types of digital signal processing equipment. The working principle of the 590BB133M000DGR oscillator is based on the feedback from two ceramic resonators and a Schottky diode, which regulates the output amplitude, ensuring a consistent frequency.
