Selection tip: if your system budget is phase-noise-limited (PLL/LO), consider an HP option; if your node is outdoors, consider a WT option.
Applications
Where these specs matter: stable frequency and low phase noise reduce PLL wander and improve synchronization margin in real timing chains.

FAQ
What output options does FVT-7S support?
Clipped-sine (0.8 Vp-p) or CMOS output. CMOS levels are specified as VOH ≥ 0.8·Vcc and VOL ≤ 0.2·Vcc.
What is the frequency stability over temperature?
±2.0 ppm over −30 °C to +75 °C, and ±2.5 ppm over −40 °C to +85 °C (option dependent).
Can I request samples or custom frequencies?
Yes. We support samples, volume production, and customization (frequency, output type, supply, and pull range). Send your target conditions for quick routing.
Is pricing shown on the page?
Pricing is quotation-based. Send your RFQ with quantity, frequency, output type, supply voltage, temperature range, and delivery terms for a fast response.
What are typical lead time and MOQ?
MOQ and lead time depend on configuration and availability. Share your requirements and forecast; we will confirm sample and production schedules accordingly.
Application engineering support: share your timing architecture (PLL, LO, SyncE/PTP, GNSS discipline), phase-noise targets, and environmental limits. We will recommend the right TCXO/VCTCXO option and validate selection paths.
