The working principle of the 510BAB156M250BAGR oscillator is based on the negative resistance characteristic of the quartz crystal resonator. The quartz crystal resonator is an electronic component that shows electrically negative resistance between its two electrodes when a voltage is applied to them. It is this negative resistance characteristic that makes the quartz crystal resonator capable of oscillation and stability.

In the 510BAB156M250BAGR oscillator, the oscillation of quartz crystal resonator is controlled by a pair of amplifier stages connected in an astable multivibrator configuration. The astable multivibrator consists of two connected transistors and two resistors. When the oscillator is powered on, the voltage at the base of the transistor is low and the transistor is in a non-conducting state. When the capacitor charges it causes the voltage to rise and the transistor becomes conductive. The rising voltage is then applied to the base of the other transistor, causing it to conduct, and the voltage on both transistors’ collectors falls accordingly. The current flowing through the crystal causes it to oscillate, producing a voltage at the output of each amplifier stage. This voltage is then amplified and the quartz crystal is tuned to a specific frequency.

The frequency of the oscillator can be easily changed by adjusting the value of resistors in the circuit. This makes it possible to generate signals with a variety of frequencies according to the application. As the oscillation frequency of quartz crystals is temperature-dependent, the frequency of the oscillator is also stable and is not affected by temperature.

In summary, the 510BAB156M250BAGR oscillator is a type of oscillator used to generate an individual frequency signal. It is mainly used in FM receivers, electronic timepieces and digital logic circuits. Its working principle is based on the negative resistance characteristic of the quartz crystal resonator and the astable multivibrator configuration. This oscillator can be tuned to a specific frequency by adjusting the value of resistors in the circuit and is not affected by temperature.
