Oscillators
A crystal oscillator is an electronic circuit that uses a quartz crystal to generate a specific frequency. Crystal oscillators are highly precise and typically exhibit deviations of less than 100 ppm.
In practice, crystal oscillators serve as timing sources in radios, processors, quartz watches and microcontrollers.

The right impulse for your technology
Quartz refers to a crystal resonator – an electronic component used in crystal oscillators that generates a precise electrical frequency. Unlike oscillators, crystal resonators require an external driving circuit to oscillate, making them a more cost-effective solution.

FAQs
What is the difference between a crystal and an oscillator?
A crystal generates a stable frequency but requires an external driving circuit. An oscillator, on the other hand, is a self-contained timing component with integrated electronics.
What frequency ranges are available?
Typical frequencies range from a few kilohertz to over 100 MHz – depending on package type and application.
Are there solutions for 5G or IoT?
Yes, our TCXO and VCTCXO products are optimized for high-precision frequency control in modern communication systems such as 5G and IoT.
