Working Principle

The AOCJY3A-13.000MHZ-SW oscillator uses an open loop frequency synthesizer circuit. The basic concept is to combine several crystal oscillators of different frequencies into a single circuit. The frequency synthesizer is composed of a frequency control circuit, a power amplifier circuit, and a unidirectional amplifier. The frequency control circuit uses a heating resistor to generate a temperature signal. The heating resistor is controlled by an electric field, so that the temperature signal can be tuned to a preset frequency, and the output of the frequency control circuit is used to control the power amplifier circuit and the unidirectional amplifier.

The power amplifier circuit is responsible for driving an oscillator circuit, which is composed of an oscillator resistor, a feedback resistor and a feedback capacitor. When the frequency control circuit works, the oscillator resistor is heated and its resistance changes, thus changing the frequency of the oscillator. The unidirectional amplifier is a differential amplifier, which is used to amplify the high frequency output of the power amplifier circuit, which is further output to the external device.
