Oscillators are components or circuits capable of generating a periodic, steady-state waveform. Typically, they contain an amplifying device in a closed-loop configuration which produces an oscillating output signal without requiring an input. They are widely used in many electronic systems since they are able to generate signals of a given frequency with very high precision and stability.

The SIT1602BC-82-XXS-33.333000X is a type of programmable oscillator suitable for a wide range of applications. It is a voltage-controlled oscillator (VCO) that can generate a sinusoidal waveform in the frequency range of 33.333MHz, whose amplitude can be set externally. The frequency of the sinusoidal waveform output by the oscillator can be varied by adjusting the external voltage applied to the control terminal.

The oscillator consists of two major components, the voltage-controlled oscillator (VCO) and the phase/frequency detector or charge pump circuit. The VCO is a type of LC oscillator and consists of two LC tanks connected in series. The LC tank circuit consists of an inductor and a capacitor, in which the inductor resonates with the capacitor to form a sinusoidal oscillation. The two LC tanks are connected in series and the output voltage of one tank is fed to the input of the other, causing the output voltage of the second tank to go in the opposite direction. This ensures that the output is a sinusoid with twice the frequency of the first tank.

The phase/frequency detector or charge pump circuit is used to provide the feedback signal to the VCO. A phase difference is generated between the phase and frequency of the output of the VCO and the feedback signal, which is then rectified and used as the amplitude control voltage to the VCO. The amplitude control voltage varies the amplitude of the output voltage and thus controls the frequency of the output sinusoidal waveform.

The SIT1602BC-82-XXS-33.333000X oscillator can be used in a variety of applications such as frequency synthesizers, clock generators, radio transmitters and receivers, and signal generators. It is an ideal choice for applications requiring precise, stable sinusoidal signals of a given frequency in the frequency range of 33.333MHz.
