The basic working principle of a 595AF140M000DGR oscillator is quite simple. The oscillator itself is made of a two-stage LC resonator. The center frequency of the LC oscillator is determined by the inductors and capacitors. An external input voltage controls the frequency of the oscillator. When the changed voltage is applied to the external control pin of the oscillator, the DC potential of the oscillator\'s tuned circuit increases or decreases. As a result, the LC oscillator frequency changes and creates a stable oscillation.

The main components of the 595AF140M000DGR include the tank circuit, the amplifying circuit, the transistors, and the feedback signal. The tank circuit consists of an inductor and a varactor. It’s responsible for providing the basic oscillation. The amplifying circuit, composed by two transistors, amplifies the electrical wave of tanks circuit so as to get a higher output power. The feedback signal is responsible for providing feedback and self-regulating the oscillator.

In conclusion, the 595AF140M000DGR oscillator is a kind of Frequency-Controlled Voltage Controlled Oscillator, with a range of applications and various advantages. Its working principle consists of a two-stage LC resonator, driven by an external input voltage which largely controls the frequency of the oscillator.
