Applications
In GNSS receivers and wireless modules, the reference oscillator directly influences lock time, frequency accuracy, and phase-noise-related performance. A compact TCXO/VCTCXO like FVT-2S helps maintain stable operation under real-world temperature and power conditions — without consuming excessive PCB area.
Where FVT-2S fits best
- GPS and GNSS modules (stable reference for RF/PLL and baseband timing)
- IoT terminals & edge sensors (low-power duty-cycled clocks)
- Mobile phones and communication devices (space-constrained reference clock)
- Sync/GNSS/Satcom timing nodes (robust timing reference selection)
- WLAN / WiMAX modules (clean reference for frequency synthesis)
Why these specs matter
- ±2.0 ppm @25°C tolerance helps protect the system frequency-error budget.
- ±0.2 ppm vs VDD/load improves robustness when supply and input loading vary.
- Low phase noise supports cleaner PLL synthesis and better RF performance.
- ≤1.5 mA helps extend battery life in always-on or intermittent GNSS/IoT modes.

Frequently Asked Questions
Can I request a specific frequency for the FVT-2S?
Yes. Share your target frequency (MHz), supply voltage, and temperature range. We will confirm feasibility and provide a matching configuration.
Do you provide samples? How can I request them?
Yes. Submit an RFQ with model, frequency, VDD, temperature range, and required quantity. Our team will recommend the best-fit option for evaluation.
What are the MOQ and lead time?
MOQ and lead time depend on frequency and configuration. Popular frequencies typically have better availability. Please request an RFQ for an exact schedule.
Can you customize frequency/voltage/temperature/output?
Yes. We support customization for frequency, supply voltage, temperature grade, and documentation/screening options. Tell us your requirements and we will propose a suitable spec.
Do you provide test or inspection reports?
Shipment test data can be provided. If you need qualification reports or batch-level documentation, specify it in your RFQ or purchase order.
Why is there no price on this page? How do I get a quote?
This is a B2B RFQ page. Pricing varies by configuration and quantity. Please contact us to receive an official quote.
Is the clipped-sine output compatible with typical RF IC reference inputs?
In many GNSS/RF designs, a 0.8 Vp-p clipped-sine reference is compatible via AC coupling. Confirm interface requirements with your chipset vendor and the FVT-2S datasheet.
