Oscillators

Oscillators are automatic circuit devices which generate electronic signals of a specific frequency, commonly applied in synchronizing circuits, timing, or as an amplifier driver. There are several types of oscillators including the digital, analog and hybrid oscillators. This article will mainly focus on the application field and working principle of the DSC1122BE2-150.0000T oscillator.

Application Field

DSC1122BE2-150.0000T is a multi-frequency oscillator. It features excellent jitter performance and frequency stability, which can better guarantee that devices that are connected to the oscillator function properly. Generally speaking, DSC1122BE2-150.0000T is often used in many kinds of digital communication equipment and consumer electronic products like cell phones, modems, satellite receivers, digital TVs and robots etc.

Working Principle

DSC1122BE2-150.0000T oscillator adopts the Pierce oscillator, which is a type of LC oscillator consist of an amplifier, a coupling capacitor and an LC resonator in series. The DC amplification device (e.g. transistor) can act as an amplifier and generate a phase shift controlling the oscillating frequency. The amplifier is connected to its output and input port, with a capacitor connecting between the two ports to form a feedback amplifier. The power of the power amplifier can give enough energy for the LC resonator. The LC resonator consists of a coil and capacitor in series and forms a tuned circuit. When it is connected to an oscillating circuit like the amplifier, the current in the LC resonator oscillates and produces an AC voltage between the two ports of the amplifier. This AC voltage forms a feedback loop, and consequently the oscillator outputs an oscillating signal.

Conclusion

To conclude, the DSC1122BE2-150.0000T oscillator is a type of Pierce oscillator which is mainly used for various digital communication devices and consumer electronics. The working principle of the oscillator relies on the use of an amplifier and LC resonator to generate an oscillating signal which can be used to synchronize and time different electrical circuits.
