653L15555C3T

The 653L15555C3T oscillator is an electronic device used for generating an alternating current or voltage signal. It is made up of a special type of oscillator circuit wherein the current feedback is used to regulate the frequency of the output signal. This type of oscillator is often used in audio-frequency applications.

The 653L15555C3T oscillator is designed to provide an exact frequency output signal and is considered to be one of the most reliable and accurate oscillators available. It is capable of operating at a frequency range of 15-33 MHz and at an output level of up to 2.5V peak-to-peak. The oscillator utilizes a Limiting Amplifier which is composed of an amplifier and a limiter. The Limiter is used to regulate the maximum voltage output so that no distortion occurs. The 653L15555C3T oscillator is also equipped with an adjustable gain control to provide the desired output signal level.

The 653L15555C3T oscillator is commonly used in applications such as RF radios and cellular phones, transceivers, remote controls, and test equipment. It is also used in audio applications, including the generation of high-fidelity sound signals. It has been extensively used in the field of medical diagnostics and laboratory testing. Additionally, because of its stability and accurate output, it is becoming increasingly popular in telecommunications systems.

The working principle of the 653L15555C3T oscillator is based on the operation of two amplifier stages in cascade. The first stage is a limiting amplifier, which limits the maximum voltage that can be achieved in order to prevent distortion in the output signal. The second stage is an adjustable gain control amplifier, which is used to control the output voltage of the oscillator.

The output signal from the adjustable gain control amplifier is then fed back into the input of the limiter, which modulates its output voltage to provide the desired frequency. The oscillator is designed to operate at a frequency-locked condition, meaning that the frequency of the output signal remains constant regardless of input signal amplitude. This makes the 653L15555C3T oscillator an ideal choice for applications that require a highly stable and accurate output signal.
