FEATURE
Product Description
FVT-3S TCXO — 3.2×2.5mm clipped-sine, ±2.0ppm stability
A compact 3225 SMD TCXO built for reference timing in GNSS receivers, IoT terminals and wireless modules. Low current draw helps extend battery life, while low phase noise supports clean PLL locking and better RF performance.
Test conditions (summary): TA=25°C unless noted; output load 10kΩ // 10pF; phase noise measured at 19.2MHz reference.

FAQ
Do you publish pricing online?
Pricing is quote-based due to configuration (frequency, voltage, temperature grade) and volume. Please send an RFQ via the Contact page.
What are MOQ and lead time?
MOQ and lead time depend on frequency, voltage option and temperature grade. Share your target spec and quantity and we will confirm availability and schedule.
Can I request samples or a custom frequency?
Yes. Samples are available for evaluation, and custom frequencies within 10–52MHz can be supported. Contact us with your target frequency and application.
What is the output signal format and how is it typically used?
FVT-3S provides a clipped-sine output (~0.8Vp-p). It is commonly AC-coupled into PLL/RF reference inputs; recommended load is 10kΩ // 10pF.
Can you provide test reports (e.g., phase noise, resistance checks, inspection)?
We can provide standard inspection and test information per shipment, and can discuss additional reporting needs for specific programs. Share your requirements in the RFQ.
