What are Oscillators?

Oscillators are self-acting oscillation generators. In electrical engineering, oscillator usually stands for an oscillator circuit that generates a sinusoidal alternating voltage.

In a narrower sense, a crystal oscillator is a ready-built oscillator circuit (IC) which is installed in a package together with the frequency-determining quartz crystal and is available as a standard component (XO).

Depending on the requirements, there are different oscillator types.

What are Oscillators needed for?

Quartz oscillators produce a stable clock signal and are therefore often found as clock generators for processors, microcontrollers, radios and in quartz clocks.

The strength of quartz oscillators lies in their high accuracy and frequency stability. The deviations of the nominal frequency are small and are less than 10 ppm.

While PXOs are used in common applications, TCXOs are used when greater temperature stability is required. VCXOs are a voltage-controlled quartz oscillator whose frequency can be changed by means of direct current.

We are happy to help you find the right oscillator for your application.
