Introduction: Oscillators Overview

Oscillators are electronic components used to generate a periodic signal of a fixed frequency. They have many applications in signal conditioning, communications, and time keeping. Oscillators can be powered by either direct current (DC) or alternating current (AC). In addition, they may be either analog or digital.

KC7050Y200.000P20EZU Application Field and Working Principle

The KC7050Y200.000P20EZU is an oscillator manufactured by Kaitsing, designed for use in a wide range of applications. The oscillator has a wide temperature range (0℃ to 70℃) and high frequency accuracy (60ppm). It has an operating voltage range of 1.6V to 5.2V and an operating current of 2.8mA. The main application of the KC7050Y200.000P20EZU is in communications systems. It is well-suited for signaling for GSM/EDGE (Enhanced Data Rates for GSM Evolution) and WCDMA (Wideband Code Division Multiple Access) networks. Additionally, the oscillator is used in satellite communications and for controlling and timing of high-speed logic. The working principle of the KC7050Y200.000P20EZU is based on hysteresis. In essence, it is an LC oscillator with a hysteretic control circuit. The oscillator has two leads, the power input and the output. The input receives a DC voltage, which is then applied to an LC tank circuit. This energizes the tank circuit, causing it to oscillate at its resonant frequency. The output of the oscillator is then fed into a hysteretic feedback circuit which is tuned to the frequency of the LC tank circuit. When the frequency drops below the tuned level, the feedback circuit causes a boost in the gain, pushing the frequency back up. When the frequency rises above the tuned level, the feedback circuit reduces the gain, pushing the frequency back down. Through this feedback loop, the circuit is able to oscillate at the desired frequency.

Conclusion

The KC7050Y200.000P20EZU oscillator is designed for use in a wide variety of applications. Its wide temperature range and high frequency accuracy make it suitable for many types of communication systems, including GSM/EDGE and WCDMA networks, satellite communication, and high-speed logic control. The oscillator operates on the principle of hysteresis, using a hysteretic feedback circuit to maintain the frequency at the desired level.
