Introduction

Oscillators are important components in the entire electronic engineering, for example, it is used in acoustics, aerospace, communications, computers and other fields. It is particularly important in wireless communication systems because it provides the necessary reference signals to the system. One of the most commonly used signal source is the AX7DBF4-983.0400T, the Oscillating IC. The content introduced in this paper will include its application fields and working principles.

Application Field

First of all, let\'s take a look at its application field. AX7DBF4-983.0400T is an oscillator which uses the principle of free-running relaxation oscillations. Its design combined with a single RC network acts as an oscillator with low distortion and wide frequency range. It is suitable for use in various applications, including:

• Power line signaling
• Multi-frequency signaling
• Audio transmission
• Tunable oscillators
• Automated sensor systems
• High voltage power isolation and surge protection circuits
• Clocks synchronization
• Digital watch circuits
• Wireless communication systems
• Digital signal processing
• Medical device measurement

This oscillator is often used in the digital wireless communication systems such as GSM/GPRS/CDMA/UMTS/WiFi/Bluetooth, for this reason it is required to maintain a high control accuracy for the signal source. This oscillator can provide reliable signal sources and its stability is stable enough, therefore it meets this requirement.

Working Principle

We mentioned it is an oscillating IC, the specific working principle is as follows. AX7DBF4-983.0400T operates on the principle of hysteresis oscillation to generate a sustained oscillation with low distortion and wide frequency range. This component consists of an amplifier, a capacitor and an inductor connected in series. The signal is input into the circuit, and the capacitor acts as an energy storage device. When the voltage across the capacitor reaches its peak, the inductor is used to reduce the voltage. The capacitor then slowly discharges the energy. The output of the circuit is an alternating current of the same frequency as the input. This type of oscillator can be tuned by changing the value of inductor, which enables the frequency of operation to be adjusted.

Conclusion

The AX7DBF4-983.0400T is an oscillator used in many applications. Its working principle is based on the principle of hysteresis oscillation, which enables it to produce a sustained oscillation with low distortion and wide frequency range. Its application fields are power line signaling, audio transmission and wireless communication systems. It is an important signal source for digital wireless communication system because its stability is stable enough.
