Oscillators: 520R15HT16M3690 Application Field and Working Principle

Oscillators, as the basic element of most electromechanical and electronic devices, play very important roles in modern circuits. The 520R15HT16M3690, as a type of oscillators, have a wide range of application fields and a very complex working principle. So, it is quite important to understand the working principle and the application field of this oscillator. First, take a look at the application fields of the 520R15HT16M3690. It is a voltage-controlled oscillator for producing frequency to serve as a time base and reference clock in telecommunications, computer system, test systems, and instrumentations. It can also be used in other electronic systems which need sinusoidal output. Therefore, 520R15HT16M3690 is suitable for any communication, radar and navigation related application.It is worth noting that this type of oscillator is characterized by its wide frequency range that can be varied from 100KHz to 800KHz, 8M-16M, with 16M being 20% off from center. Its output amplitude is usually within 5M-14M, which again with 14M being 20% off from center.Now, let\'s move on to its working principle. It is based on the Pierce oscillator circuit, which has two stages of amplifying, one RC coupled amplifier, and two capacitors serving as frequency determining elements. To be more specific, the 540R15HT16M3690 has two transistors in it, an NPN transistor and PNP transistor. These transistors can be regarded as controlling each other by their operating points and the transferred signal. The NPN transistor works as an amplifier circuit, and the PNP transistor is a tuned circuit. This combination allows the signal of the crystal lattice to be biased between two transistors, and vibrates at the specific frequency. Those vibrations can greatly amplify output, leading to an oscillation.To sum up, the 520R15HT16M3690 is an important type of oscillators, and can be used in a wide range of application fields. Its working principle is based on the Pierce oscillator circuit, which combines two transistors and produces oscillation with a wide and precise frequency range.
