Oscillators: 353SB3I320R Application Field and Working Principle

Since their inception in the mid-20th century, oscillators have found applications in numerous industries, especially telecommunications, where they are used to generate signals of a specific frequency. Today, crystal oscillators are widely used due to their stability and reliability. The 353SB3I320R is one such example of a crystal oscillator developed by Symmetry Electronics to improve the efficiency of communications systems. This article outlines the application field and working principle of the 353SB3I320R.

Application Field & Working Principle

The 353SB3I320R is an idiostable crystal oscillator that is compatible with various systems in the telecom industry, such as Ethernet and GPRS. At its core, it utilizes a quartz crystal resonator to generate a frequency of 200 kHz, and due to its stability and robustness, it is suitable for the long-term monitoring of communication systems. In addition, the 353SB3I320R is equipped with an external capacitor, allowing it to be tuned to different frequencies and thus, making it suitable for different applications. The device is also sealed with a protective epoxy resin, providing protection against dust and other corrosive elements. The 353SB3I320R operates on a basic operating principle. In essence, the oscillator passes a current through the quartz crystal, causing it to vibrate and generate a frequency of 200 kHz. This frequency is then amplified by the transistor and passed through a filter to smooth out any anomalies in the frequency. This filtered frequency is then used to drive the communications module, which is responsible for transmitting the signal. The 353SB3I320R is thus suitable for a wide range of applications such as audio and video broadcast systems, satellite communications systems, and local area networks. It is also compatible with a variety of oscillator circuits, such as Pierce, Clapp, and Colpitts oscillators, thus allowing it to be used in various kinds of systems. In terms of performance, the 353SB3I320R has an excellent frequency accuracy of +/- 1.7 ppm, making it very reliable and offering a level of precision that is essential for communication systems. It also has a wide operating temperature range, with options ranging from -30°C to +85°C, allowing for use in a variety of environments. Finally, the 353SB3I320R offers a high-level of integration, making it ideal for applications where space is at a premium. It is therefore ideal for telecommunications, where it can provide an efficient and reliable solution for signal transmission.

Conclusion

The 353SB3I320R crystal oscillator offers a reliable and efficient solution for signal transmission in the telecommunications industry. Its frequency accuracy and stability make it suitable for long-term monitoring, and due to its wide operating temperature range, it is suitable for use in a variety of environments. Its small size and simple operating principle make it easy to integrate into various systems, making it an ideal option for applications where space is at a premium.
