Introduction

Oscillators are electronic components that create periodic vibrations or oscillations that can be used in a wide variety of applications. Among them is the Application-Specific Communications Oscillator (ASCO­) 18.432 MHz EK­T, which is designed for specific radio communications applications. This article will discuss the application field and the working principle of the ASCO-18.432MHz-EK-T oscillator and how it is used in applications.

Application Field of ASCO-18.432MHz-EK-T Oscillator

The ASCO-18.432MHz-EK-T oscillator is designed to be used in applications with strict requirements on low phase noise and high stability at low power consumption. These include cellular and trunk radio applications as well as wireless local area networks (WLAN), wireless mesh networks, and radio transmission systems.The oscillator is also suitable for use in applications where a wide range of frequency tuning is required, such as test and measurement systems, radio modems, and global navigation satellite systems (GNSS). Additionally, the ASCO-18.432MHz-EK-T is used in industrial and military communication systems.

Working Principle of ASCO-18.432MHz-EK-T Oscillator

The ASCO-18.432MHz-EK-T oscillator works on the principle of electronic resonance. It uses an integrated quartz resonator in order to achieve low phase noise and stability at low power consumption. The frequency of the oscillator is determined by the frequency of the quartz resonator, which can be tuned to an exact frequency. The resonator functions like a tuning fork - when voltage is applied to the quartz crystal, it vibrates at a certain frequency that is determined by its shape, size, and other factors. The oscillator also uses a voltage-controlled oscillator (VCO) to generate and maintain the frequency. The VCO and the quartz crystal are connected in a closed loop, and the frequency of the oscillator is determined by the frequency of the quartz crystal. By varying the voltage applied to the quartz crystal, the frequency of the oscillator can be adjusted to match the desired frequency. This allows the oscillator to be used for frequency synchronization and testing applications.

Conclusion

The ASCO-18.432MHz-EK-T oscillator is a specialized oscillator designed for specific radio communications applications. It works on the principle of electronic resonance, using an integrated quartz resonator and voltage-controlled oscillator to achieve low phase noise and stability at low power consumption. The oscillator is suitable for use in applications where a wide range of frequency tuning is required, such as cellular and trunk radio systems, WLAN, wireless mesh networks, and industrial and military communication systems.
