Ultra Low Phase Noise 10MHz SMD OCXO – High Precision Reference

Product Overview：

Our 10MHz OCXO is a high-performance, oven-controlled crystal oscillator housed in a compact SMD package. Designed for mission-critical applications, it offers ultra-low phase noise performance (up to -115 dBc/Hz at 1Hz offset) and exceptional short-term stability (Allan Variance of 0.002 ppb). This series features an integrated electrical frequency tuning input and a reference voltage output, making it easy to integrate into complex microwave systems.

Key Features：

Ultra-Low Phase Noise: Multiple options available, reaching -115 dBc/Hz @ 1Hz and a noise floor of -170 dBc/Hz.
Compact SMD Design: Ideal for space-constrained PCB layouts without sacrificing stability.
Exceptional Stability: Tight frequency stability options from ±5 ppb to ±100 ppb.
Superior Allan Variance: 0.002 ppb (t=1 sec), ensuring ultra-precise short-term timing.
Fast Warm-up Time: Reaches stability within 5 minutes at 25°C.
Rugged Construction: Built to meet MIL-STD-202 standards for vibration and shock.
Easy Integration: Includes Electrical Frequency Tuning (VCO Input) and Reference Voltage Output.

Applications：

Radar Systems: Low phase noise ensures superior target detection and signal clarity.
Test & Measurement: High-stability reference for frequency counters and synthesizers.
Microwave Communication: Critical for clock references in microwave signal sources.
Telecom Systems: Reliable synchronization for high-speed data networks.
