Frequently Asked Questions

Why do clocks use 32.768kHz crystal oscillators?

32.768kHz is a power-of-two frequency (2^15), making it ideal for binary counters in real-time clocks. It allows precise timekeeping with low power consumption, commonly used in watches, microcontrollers, and IoT devices.

What is a VCXO?

A Voltage-Controlled Crystal Oscillator (VCXO) uses an AT-cut quartz resonator with a variable capacitor in the circuit. Applying a control voltage adjusts the oscillation frequency slightly, useful in phase-locked loops and synchronization systems.

Are your products RoHS compliant?

Yes, all ChipSun products comply with RoHS, REACH, and other environmental protection regulations. We provide material declarations and test reports upon request.

Do you offer custom frequency components?

Yes, we offer full customization including frequency, package size, load capacitance, stability, and operating temperature. Contact our engineering team for design support.
