653P148B6A2T Working Principle

Quartz crystal resonator is the core of 653P148B6A2T oscillator which is able to produce accurate output signals. It consists of a quartz crystal, an oscillator circuit, an amplifier, a voltage regulator, and an output buffer. The quartz crystal is the key part of the 653P148B6A2T oscillator since it is capable of the frequency oscillation.

This oscillator works with a quartz crystal and oscillations are generated via the oscillator circuits. Generally, a quartz crystal has a fundamental frequency range of 10 MHz to 30 MHz, while its overtone frequency ranges from 30 to 100 MHz. The oscillator circuit is designed so that when the crystal is vibrated, it can generate a signal with a specific frequency which is the same as the fundamental frequency of the crystal. The signal is then amplified, regulated and buffered to generate a stable output signal.

In order to hold the frequency stable, the oscillator circuit is designed in terms of a negative feedback system. When the signal output of the crystal resonator, amplified by the amplifier, is fed back to the crystal resonator, a negative feedback between the output and the crystal results in a final output frequency which is the same as the fundamental frequency of the crystal. The output frequency is thus determined by the characteristics of the crystal.

In conclusion, 653P148B6A2T oscillator is widely employed in many circuits and applications due to its good performance, stability, and low power consumption. Its working principle is based on the use of a quartz crystal resonator and a negative feedback system. It is a highly reliable and efficient device that can be used for many different applications.
