Oscillators are electronic circuits typically found in electronic devices which produce a periodic, oscillating waveform. Their main purpose is to bring stability in timing, or to serve as a time reference. Without oscillators, many of the most modern electronic devices such as mobile phones, computers and digital systems wouldn’t be able to function.

Types of Oscillators

Oscillators can be divided into two main types: digital and analog. Digital oscillators rely on digital logic components such as gates or microcontrollers, and are mainly used in time keeping applications. Analog oscillators contain a physical mechanism, such as a quartz crystal or magnet, to produce a regular, periodic signal.

The 590FB403M000DG (hereafter, the “DG”) is a trend-setting piezoelectric ceramic resonator crystal that falls into the analog oscillator category.

Application Field and Working Principle

The DG\'s main application is in radio systems such as satellite receivers, car radios, iPhone and other cell phones, tablets, etc. It is also used in LCD displays and medical equipment. The DG\'s specific characteristics require it be used as an oscillator circuit. The five main components of the DG circuit are a quartz crystal, two capacitors, an inductance coil and an illustrated resistor. When a voltage is applied to the circuit, the components resonate, creating an oscillating output signal.

The DG operates at a specific frequency, usually between 6.0 and 40MHz. Operating frequency and stability are determined by the device\'s internal components. The accuracy of the DG’s oscillation can be adjusted by changing the two capacitors inside the circuit. This is called frequency tuning. The frequency adjustment range is +/- 20ppm, which is unmatched by any other oscillator device in the same price range.

Conclusion

The 590FB403M000DG piezoelectric ceramic resonator crystal is the industry leader in low cost, reliable oscillator solutions. With its many advantages, such as wide frequency range, precise, adjustable frequency tuning and design innovation, it is an ideal choice for many of today\'s most advanced electronic circuits.
