Introduction to Oscillators

Oscillators are electronic circuits that generate an oscillating waveform, typically using the time-varying output of active devices such as transistors or operational amplifiers. Oscillators are used in many applications, ranging from digital signal processing, control systems, and power supplies to communication systems.

SIT1602BC-12-25E-38.000000D Application Field and Working Principle

SIT1602BC-12-25E-38.000000D is a low-frequency sinusoidal oscillator based on a two-stage crystal filter. This oscillator is especially suitable for HF and VHF communications as it features low power consumption, low distortion, high stability and a wide range of operating frequencies.The SIT1602BC-12-25E-38.000000D oscillator operates by generating sinusoidal output from a harmonic oscillator circuit. The harmonic oscillator in this oscillator consists of a pair of crystals, which are connected in series in a bridge circuit and driven by a constant voltage. The crystal is chosen to give a frequency that accurately reflects the desired output frequency. The bridge circuit serves to amplify the output signal from the crystals and to cancel out the input DC bias. The output of the harmonic oscillator circuit is then passed to a bandpass filter which is used to filter the harmonic content of the output signal and provide an output which is sinusoidal in shape. The bandpass filter can also be tuned to allow it to filter the output signal and adjust the frequency as required. The SIT1602BC-12-25E-38.000000D oscillator is used in many different applications, such as HF and VHF communications, digital signal processing, control systems, and power supplies. It is ideal for use in applications where low power consumption and high stability are required.
