Oscillators: DSC1122AE1-100.0000

Oscillators have been used in a wide variety of fields, playing a critical role by supplying a continuous source of real-time data. In this article, we will look at the DSC1122AE1-100.0000 oscillator, its application fields and working principle.

What is DSC1122AE1-100.0000?

DSC1122AE1-100.0000 is a high frequency, low power, low phase noise surface-mount ceramic dielectric resonator oscillator, developed to provide high accuracy and low jitter performance in a small package size. It operates in the range from 13MHz to 130MHz and features a stability level less than ±25ppm, with a lower Temperature Coefficient of 0.01ppm/°C. It also comes with a 3-bit configurable output clock source and a number of external control pins, providing the user with flexibility in terms of frequency selection and performance.

Application Fields

The oscillator is mainly used in communication applications, providing reliable frequency sources in wired or wireless communication systems. Such as, the oscillator can be used in Bluetooth modules, radio transmitters, receivers, and digital radio broadcasting systems. Additionally, it is applied in other applications, including: military & aerospace, medical instrumentation, satellite communication, and automotive applications.

Working Principle

The DSC1122AE1-100.0000 is composed of a single-piece dielectric resonator which consists of a quartz crystal, connecting two electrical plates. The quartz crystal contains two layers of quartz, each layer possessing different piezoelectric functions. This allows the device to resonate at its own frequency when a predetermined electric signal is applied. The oscillator utilizes a CMOS inverter circuit and drive pulses to excite the internal quartz crystal resonator. This results in the development of an output clock signal with a frequency that matches the resonator. The frequency of the output signal is determined by the design parameters of the DSC1122AE1-100.0000 oscillator.

Conclusion

The DSC1122AE1-100.0000 is a high-frequency, low-power, low-phase noise surface-mount ceramic dielectric resonator oscillator. It is used in communication applications for providing a reliable frequency source and also in other areas, such us military & aerospace, medical instrumentation, satellite communication, and automotive applications. The working principle of the oscillator is based on the resonance of a quartz crystal driven by a CMOS inverter circuit.
