High Precision Series

When Your Timing Budget Has No Room for Drift

Engineered for mission-critical applications that cannot tolerate frequency drift over time, temperature, or voltage variations. Every parts built to tighter stability windows where every ppm counts.

Stability Grades Across the Series

OCXO
Highest frequency stability
±3 ppb to ±50 ppb 
TCXO
Temperature-compensated precision
±0.05 ppm to ±2 ppm
Precision XO
Cost-efficient precision
Down to ±10 ppm
100% FINAL ELECTRICAL TESTING
Verified Before Shipment
Every oscillator is electrically verified against its specified frequency-performance limits and key electrical parameters before shipment.
*Additional screening and test documentation are available according to project requirements.

Frequency Stability Is More Than One Number

Total frequency performance include initial accuracy, temperature stability, supply variation, load variation and aging.
