Frequently Asked Questions

What's the difference between a crystal and an oscillator?

A crystal (resonator) is a passive component that requires an external oscillator circuit. An oscillator (XO) integrates the crystal and IC, providing a direct clock output.

Do you offer custom frequencies?

Yes, we supply programmable oscillators and can source custom frequencies from our manufacturing partners. Contact us with your specification.

What is the MOQ?

Standard parts have no minimum order. For volume pricing, we recommend 1k+ units. Samples are available for evaluation.

Which brands do you carry?

We are authorized for YXC, TXC, NDK, Epson, and Kyocera. Also offer VISTAR private‑label cost‑effective alternatives.
