Frequently Asked Questions

What is the difference between a crystal resonator and a crystal oscillator?

A crystal resonator is a passive component that requires external circuitry to oscillate, while a crystal oscillator (XO) is an active device with built-in circuitry that generates a stable clock signal when powered.

Do you offer samples?

Yes, sample requests can be submitted through the official website. Evaluation units are available for qualified design projects.

Are your products suitable for automotive applications?

We offer AEC-Q200 qualified components including high-temperature oscillators and ruggedized crystals designed for automotive electronics and ADAS systems.

What packaging options are available?

We support a wide range of SMD and DIP packages, including ultra-small 1612, 2016, 2520, 3225, and cylindrical HC-49/S.
