Working Principle

The basic principle of the programmable oscillator SIT9002AI-38H18SD is through dual transmission to generate a frequency signal, which is set by the addressing and setting ports. The working process of the oscillator can be broken down into two parts. First of all, the frequency signal generated from the dual transmission will act as an external source on a resonant path and the output signal is created when it resonates with the resonance coupling composed of a capacitor and inductor. Secondly, based on the external source, the energy is constantly fed back to create a self-sustaining oscillator circuit. In addition to this, the internal structure of the oscillator composes of an inverter, a resonant path, an amplifier and an adjustable oscillating elements (AOE), which are adjustable capacitors featuring a wide range of frequencies and a wide range of operating voltages. The amplifier controls the frequency by amplifying the feedback signal from the AOE, to ensure the oscillator is always in a stable and self-sustaining state. Adjustment of output frequency can also be done digitally.
