This makes it possible to dynamically adjust the output frequency of the oscillator without changing the components inside the circuit. The circuit of the CB3-2I-3M6864 oscillator consists of three main parts: an integrated circuit (IC) containing the active components, a crystal resonator for high-frequency stability, and a voltage-controlled input. The IC contains a transistor array, which amplifies the signal generated by the crystal resonator and feeds it to the output. The input voltage is then used to adjust the output frequency of the oscillator. The higher the voltage, the higher the frequency.The frequency of the oscillator is determined by the series of capacitors and inductors inside the circuit and is tuned to the specific frequency that is required by the application. Additionally, the CB3-2I-3M6864 oscillator can be programmed to change its frequency over time, making it suitable for frequency hopping and spread spectrum radio systems.In summary, the CB3-2I-3M6864 voltage-controlled oscillator is a widely used component for various applications. It is used to stabilize the frequency of large transmitters, create low-frequency signals, and for various communications systems. It consists of an IC containing the active components, a crystal resonator for high-frequency stability, and a voltage-controlled input. The frequency of the oscillator is determined by the components inside the circuit and can be adjusted by the input voltage.
