Oscillators - 655E15625C3T Application Field and Working Principle

The 655E15625C3T is a type of oscillator, a device used in electronic circuitry to generate an ongoing, periodic waveform. They range in size and complexity and can be used for various applications in radio and audio electronics. This particular oscillator is a Frequency Locked Oscillator (FLO) designed for applications such as frequency synthesis for radios, stereo systems and other audio equipment.

Overview of Oscillator Technology

An oscillator is a type of circuit that uses a non-linear component, such as a transistor or diode, to produce a periodic waveform. The frequency of the waveform is determined by the components of the circuit, such as the values of resistors and capacitors, and can range from extremely low to very high frequencies. Oscillators are divided into two categories - amplitude-operated and frequency-operated. Frequency-operated oscillators, such as the 655E15625C3T, are known as Frequency Locked Oscillators (FLOs) and are used primarily in audio electronics.

Application Field of the 655E15625C3T

The 655E15625C3T is a frequency-locked oscillator designed for frequency synthesis applications such as tuners, radios, and other audio equipment. The device is capable of producing frequency outputs higher than 200 MHz, and is used in the design of compact and cost-effective circuits. The design of the 655E15625C3T permits the user to program the frequency, locking it within a certain range and preventing frequency drift. This feature makes the device suitable for use in applications requiring precision and accuracy, such as test equipment and RF amplifiers.

Working Principle of the 655E15625C3T

The 655E15625C3T is a frequency-locked oscillator (FLO) and as such works on the principle of frequency synthesising. Frequency synthesising uses a series of electrical signals to produce a high-frequency sine wave output. In the case of the 655E15625C3T, this signal is generated using a combination of a PLL (Phase Locked Loop) and an oscillator circuit. The PLL is used to generate a reference signal, which is then compared to an input signal to enable an oscillator circuit to produce a high-frequency sine wave output. In addition, the device has a manual frequency adjust feature that allows the user to set the desired frequency.

Conclusion

The 655E15625C3T oscillator is an example of a frequency-locked oscillator (FLO) designed to produce a high-frequency sine wave output suitable for frequency synthesising applications such as radios, tuners, and other audio equipment. The device has the advantage of a manual frequency adjust feature that allows it to be used in circuits that require precise tuning and frequency accuracy.
