Ultra Low Phase Noise OCXO Products with the Smallest Form Factor Possible
NEL Frequency Controls manufactures the most advanced oven controlled crystal oscillators on the market. Our frequency control devices come in compact, size reduced packages. Customers needing high frequency, fully characterized, ‘best in class’ phase noise crystal oscillators choose NEL Frequency Controls for their leading edge requirements. Ultra low phase noise OCXO application support is available upon request.
Why use an OCXO
Radar equipment, defense and commercial communication systems, and instrumentation equipment all require frequency sources that have very low phase noises and excellent stability over long distances. An OCXO oscillator uses a quartz crystal contained in an oven-like device that maintains a constant operating temperature to avoid changes in frequency and maintain precise accuracy.
Top reasons to choose an NEL OCXO
NEL offers a variety of OCXO devices that have low phase, ultra low phase, extraordinary low phase noise, and low power consumption properties. Our low phase noise oscillator solutions take into account power supply noise, harmonics, and shock and vibration, as well as loading, temperature, and assembly conditions. We check and validate quality at each step of production and rigorously test every product to ensure it can deliver exceptional frequency stability. NEL also provides short lead times and just in time delivery options for all of our OCXO oscillator devices.
OCXO oscillator applications
Our OCXO modules are used to maintain precise frequency stability in a wide variety of instrumentation, telecommunication, data communication, GPS, and COTS/Dual use applications. Choose from a wide range of frequencies from 8 MHz up to 500 MHz, including 10 MHz OCXO and 100 MHz oscillator devices. If you have any questions about which low phase noise oscillator is right for your application, then please reach out to our team today If you would like a quote on a specific part, please fill out and submit the Request for Quote Form.
