Oscillators

Oscillators are a type of electronic components that generate a particular waveform. An electronic oscillator can produce a regular, repetitive signal, generally of sine waveform, which is used as timing or clock signal. Oscillator circuits are used in electronic gadgets such as computers, game consoles, televisions, radios, and many other devices. Oscillators are said to be the heart of all these devices as they provide timing reference, without which most modern electronic gadgets and equipment would not be able to operate properly.

DSC1121CI2-168.0000T Application Field and Working Principle

The DSC1121CI2-168.0000T oscillator is a low jitter high frequency voltage controlled oscillator (VCO) designed for use in communication and test equipment. The oscillator is capable of operating up to 1.8 GHz with low phase noise. It is a compact package of 18x20 mm, making it suitable for applications where space is limited.

The working principle of the DSC1121CI2-168.0000T is based on a voltage controlled oscillator, where the frequency is determined by the supply voltage. The oscillator has a number of PLLs, (phase locked loops), whose "charge pumps" force a voltage on a variable capacitor. This variable capacitor then acts as the frequency-determining element. By adjusting the voltage, the frequency can be controlled with high accuracy.
