Ultra Low Phase Noise 100MHz OCXO – High Stability Oven Controlled Crystal Oscillator
Introduction:
Our 100MHz OCXO is engineered for applications requiring industry-leading frequency stability and ultra-low phase noise performance. With a noise floor reaching -180 dBc/Hz, this oscillator provides the precision timing required for advanced telecommunications, radar systems, and high-end measurement instrumentation.
Key Features:
Exceptional Phase Noise: -110 dBc/Hz @ 10Hz, -165 dBc/Hz @ 1kHz, and a floor of -180 dBc/Hz.
High Frequency Stability: ±0.05 ppm over operating temperature range (-40°C to +85°C).
Low Aging Rate: Daily aging less than ±1.0 ppb and yearly aging within ±0.1 ppm.
Short-Term Stability (Allan Variance): Superior performance at < 5E-11.
Standard 5VDC Power Supply: Optimized for low power consumption (300mA operating current).
Clean Sine Wave Output: High signal purity with harmonics at -50 dBc and spurious at -80 dBc.
