Introduction to Oscillators

An oscillator is a device or circuit that produces a periodic electronic signal, often a sine or square wave form. It is used as a timing reference for the rest of the circuit and can cover a wide range of applications. Oscillators are used in frequency synthesisers, in communication circuits, in control systems, as well as in many other devices and instruments.

353SB5C260R Application Field and Working Principle

353SB5C260R, manufactured by Murata, is a SMD Temperature Compensated Crystal Oscillator (TCXO) which operates from a frequency of 10 MHz to 156.25 MHz. This TCXO is commonly used in communication, audio, and industrial applications.

The Working Principle of 353SB5C260R

The 353SB5C260R TCXO is a quartz oscillator with an impedance-compensated crystal element and an internal frequency control circuit. The crystal is made of a piezoelectric material, such as quartz, with electrodes attached to the element to form an oscillating circuit. When an electrical current is applied to the crystal, it creates an oscillating electric field that is used to generate a clock signal of a specific frequency. This is known as the oscillator frequency.

The 353SB5C260R is also temperature compensated, meaning that the frequency of the oscillator will be stable over a wide temperature range. This is achieved by using a temperature sensor which compensates for changes in temperature by adjusting the oscillator frequency accordingly. This ensures that the oscillator\'s frequency is accurately maintained over a range of temperatures.

Application Field of 353SB5C260R

The 353SB5C260R is suitable for a wide range of applications. It is commonly used in cellular phones, GPS receivers, wireless communication base stations, automotive electronics, and industrial communication systems. It is also used in audio applications, such as professional audio mixers and PA systems, as the high stability of the frequency enables high-quality sound reproduction.

Conclusion

The 353SB5C260R is a highly stable and reliable TCXO designed for use in multiple applications. It has a wide operating frequency range, as well as an integrated temperature compensation circuit to ensure accurate frequency over a range of temperature changes. This makes it suitable for a variety of applications, such as mobile phones, GPS receivers, audio systems, and industrial communication systems.
