Characteristics and Applications of Ultra-Low Phase Noise OCXO

Characteristics of Ultra-Low Phase Noise OCXO


High Stability


Ultra-low phase noise OCXOs are renowned for their exceptional high stability. Their internal constant temperature control mechanism can ensure that the crystal oscillator maintains a very high frequency stability even under extreme temperature changes.


Low Aging Characteristics


This type of OCXO also has an extremely low frequency aging rate, meaning that its output frequency changes very little over time. The low aging characteristic ensures the reliability and accuracy of long-term operation, allowing devices to continuously provide stable time reference signals, which is especially suitable for scenarios requiring long-term high-precision timekeeping.


Ultra-Low Phase Noise Option


To meet the needs of applications with extremely high signal purity requirements, ultra-low phase noise OCXOs offer a dedicated ultra-low phase noise option. This feature is crucial for reducing signal distortion and improving the accuracy and integrity of data transmission, especially in fields such as radar systems, high-speed digital communications, and audio/video signal processing.


Multiple Output Options


To accommodate different equipment interface needs, ultra-low phase noise OCXOs support sine wave or HCMOS/TTL digital signal output. Sine wave output is suitable for analog signal processing, while HCMOS/TTL output is better suited for digital circuits. This flexibility allows OCXOs to be widely used in various electronic devices.


Using SC-Cut Crystals


To further enhance performance, ultra-low phase noise OCXOs use high-quality SC-cut crystals. SC-cut crystals are known for their excellent frequency-temperature characteristics and low noise properties, providing superior performance assurance for OCXOs.


Power Supply Voltage Options


To be compatible with the power supply needs of different devices, ultra-low phase noise OCXOs offer 5V or 12V power supply voltage options. This design allows OCXOs to be easily integrated into various electronic devices without the need for additional power conversion circuits, reducing system complexity and cost.
