It is widely used in a wide range of applications such as frequency synthesizers, precision frequency counters, modems, and communication equipments. This article will discuss the application field and working principle of 637L20002I2T oscillator.

Application Field

637L20002I2T oscillator is mainly used in a wide range of applications in various industries. The primary application of 637L20002I2T oscillator is in frequency synthesizers which are used in many different consumer-level items such as televisions, DVD players, and radio receivers. These synthesizers have become the preferred choice in the consumer industry due to their low cost and efficiency. Apart from synthesizers, 637L20002I2T oscillator is also used in modems, communication equipments, and precision frequency counters. Modems use 637L20002I2T oscillator to generate frequencies which are used to transfer data over telephone lines. In communication equipments, 637L20002I2T oscillator can be used to stabilize the signal sent from one location to another. This ensures that there is no signal loss and distortion when the signal is transmitted. Lastly, in precision frequency counters, 637L20002I2T oscillator is used to measure frequency accurately to within a few parts per million.

Working Principle

The working principle of 637L20002I2T oscillator is based on the principle of positive feedback. It consists of an amplifier, an oscillator, and a low-pass filter. In the operation of the 637L20002I2T oscillator, the amplifier is used to amplify the signal which is generated by the oscillator. The amplified signal is then passed through a low-pass filter which filters out any out-of-frequency signals. The output signal from the low-pass filter is then fed back to the input terminal of the oscillator. This creates a feedback loop which steadily builds up the frequency of the oscillator signal until a steady sinusoidal signal is produced. This signal is then further amplified by the amplifier and passed through the low-pass filter to form the output signal of the oscillator.

Conclusion

637L20002I2T oscillator is a type of oscillator developed by OCHU which features fast switching speed and low-cost production. It is widely used in a wide range of applications such as frequency synthesizers, precision frequency counters, modems, and communication equipments. The working principle of 637L20002I2T oscillator is based on the principle of positive feedback where an amplified signal is generated from an oscillator and is then passed through a low-pass filter before being fed back to the input terminal of the oscillator.
