591EB200M000DGR Application Field and Working Principle

The 591EB200M000DGR is an oscillator component consisting of semiconductor, oscillator matrix and crystal resonator. It has a wide application field, and the main application fields are communications, medical, industrial control, military, aerospace and automotive.

The oscillator mainly consists of oscillation amplifier and crystal resonator. The oscillation amplifier includes frequency synthesizer step, power amplifier, phase comparator, filter circuit, voltage control element and voltage detector. The components in it actively adjust the frequency output of the oscillator.

At general, the operation principle of 591EB200M000DGR is based on negative feedback oscillation principle, and the principle is that the output signal is fed back into the input terminal of the amplifier, resulting in a signal self-oscillating circuit, and the long-term stable signal generated in the block diagram forming an overall oscillating system.

A stable signal is generated in the oscillator by the positive feedback from the regenerative amplifier i.e. the amplifier is connected with negative feedback between the output and input, and the system frequency is determined by the external circuit parameters. The whole system can be divided into two parts in detail, which is the positive feedback loop and negative feedback loop.

In the positive feedback loop, it consists of one crystal and feedback circuit that connect the output and input. When the input signal is a certain frequency, the output of the amplifier is fed back to the pre-amplifier for additional amplification, this is the oscillation establishment phase. That means the single crystal frequency is amplified by the amplifier and the output voltage rises to a level that allows the feedback loop to feed it back to the original input mode.

In the negative feedback loop, the feedback signal is in the same phase as the input signal and weak energy is lost, thus reducing the output voltage, so that the output of the amplifier is no longer in the usual state, thus forming a stability of oscillator.

In general, the oscillator components of the 591EB200M000DGR has excellent frequency range, stability, low power consumption, high efficiency and high reliability, and it is widely used in the communication, medical, industrial control, military, aerospace and automotive industries.
