OCXO, ultra-high stable crystal oscillator, the aircraft carrier among crystal oscillators

OCXO constant temperature crystal oscillator

OCXO (Oven-Controlled Crystal Oscillator) constant temperature crystal oscillator is a high-precision frequency stabilization device, mainly used in applications requiring high-precision time and frequency, such as satellite navigation, communication equipment, scientific research and other fields. It uses a built-in temperature control system to maintain the crystal working at a constant temperature, thereby reducing the impact of temperature and improving frequency stability and accuracy.

working principle:

The working principle of the OCXO crystal oscillator is to use a thermal circuit and a constant temperature furnace to control the temperature of the crystal. By constantly monitoring the temperature of the crystal and adjusting the constant temperature bath, the crystal is kept working at a constant temperature, thus eliminating the impact of temperature on the frequency of the crystal. The more stable the temperature of the crystal, the higher the stability of the crystal frequency.

Features:

The advantages of OCXO crystal oscillator are mainly reflected in its excellent frequency stability and vibration resistance. The frequency stability of the crystal can reach 1x10^-10 or better, which means that the frequency error is very small during long-term operation, and a large number of OCXOs will be used in 2E/3E clocks. In addition, OCXO crystal oscillators can withstand large vibrations and shocks, allowing them to maintain stable operation under harsh environmental conditions. Among crystal oscillator products, its size is larger than other passive crystal oscillators and active crystal oscillators, and its stability far exceeds other types of crystal oscillators, so it is called the aircraft carrier among crystal oscillators.

Applications:

OCXO crystal oscillators are widely used in various fields. In satellite navigation systems, OCXO crystal oscillators are used as time benchmarks to ensure the accuracy of satellite positioning. In communication equipment, OCXO crystal oscillators are used as clock sources to ensure the stability and synchronization of network data transmission. In the field of scientific research, OCXO crystal oscillators are used to provide high-precision time and frequency signals for experimental data collection and analysis.

Common OCXO frequency application cases:

10 MHz:
10 MHz is one of the common OCXO frequency points and is widely used in communications, measuring instruments, radio broadcasting and other fields.

5 MHz:
5 MHz is also one of the common OCXO frequency points and is used in some specific applications, such as military and aerospace.

30 MHz:
The 30 MHz frequency point is used for some specific applications, such as extremely high frequency (UHF) radio equipment, military combat systems, etc.

100 MHz:
The 100 MHz frequency point is suitable for some high-frequency applications, such as radio signal analyzers, high-speed data acquisition systems and other fields.

Above, these are just examples of some common frequency points. In fact, the frequency range of Hangjing OCXO can be selected from 5MHz to 400MHz, and the specific selection depends on the needs of the specific application.
