100MHz Ultra-Low Phase Noise OCXO – High-Stability Precision Timing Source

Product Overview

The 100MHz OCXO is a high-performance Oven Controlled Crystal Oscillator engineered for mission-critical synchronization and high-precision communication systems. Delivering an industry-leading phase noise floor of -180dBc/Hz and a short-term stability (Allan Variance) of <5E-11, this oscillator ensures unparalleled signal purity. With its ±0.05 ppm temperature stability and low G-sensitivity (±0.5 ppb/G), it provides reliable performance in the most demanding RF environments.

Key Features

Industry-Leading Phase Noise: Reaches -180 dBc/Hz at 100kHz and 1MHz offsets.
Exceptional Stability: Tight ±0.05 ppm frequency stability over -40°C to +85°C.
Superior Short-Term Stability: Allan deviation of < 5E-11 for precision timing.
Low Aging Rate: Daily aging less than ±1.0 ppb; yearly aging within ±0.1 ppm.
Clean Sine Wave Output: High signal integrity with harmonics at -50 dBc and spurious at -80 dBc.
Robust Environment Resistance: Low G-sensitivity (±0.5 ppb/G) for vibration-heavy applications.
Voltage Control (EFC): 0-5V tuning range with ±1 ppm adjustment for precise calibration.

Applications

Advanced Radar Systems: Ensures maximum target detection range and Doppler resolution.
Satellite Communications (SATCOM): High-purity reference for up/down conversion.
Test & Measurement Equipment: Reference clocks for high-end synthesizers and signal analyzers.
Precision Time Protocol (PTP): High-stability clock for synchronization in 5G and data centers.
