Introduction to Programmable Oscillators

Programmable oscillators are electronic devices that produce electrical signals at a range of frequencies or levels. The most common type of programmable oscillator is a voltage-controlled oscillator or VCO. This type of oscillator is typically used in applications such as automotive, data communications, audio, and video.VCOs can be commonly found in embedded systems, where they are used to provide accuracy, stability, and flexibility with respect to timing and frequency control. Programmable oscillators are also used in a wide range of applications such as radio frequency communication, radio broadcasts, wireless security systems, and more.
