In the aerospace field—from satellite navigation systems to deep-space probes, from manned spacecraft to space stations—various aerospace devices rely on highly stable crystal oscillators to provide precise time and frequency references.
In the aerospace field, from satellite navigation systems to deep-space probes and from manned spacecraft to space stations, various aerospace devices rely on highly stable crystal oscillators to provide precise time and frequency references. In satellite communications, a stable crystal oscillator frequency ensures accurate and error-free communication between satellites and ground stations, thereby preventing signal delays and errors. In satellite navigation systems, the frequency accuracy of crystal oscillators directly affects the precision of positioning; even a tiny frequency deviation can lead to positioning errors of several kilometers or more. For deep-space probes tasked with complex missions, highly stable crystal oscillators guarantee precise synchronization among the probe’s various instruments and equipment as well as the accuracy of data acquisition—making them one of the key factors determining whether the probe can successfully complete its mission.
Taijing High Precision TCXO Clock oscillator technology advantages
1. High Precision and Temperature Stability
Employing advanced temperature-compensation technology, this device maintains a high frequency stability of ±0.5 ppm over a wide temperature range from -40°C to +105°C. Within the temperature range from -40°C to +85°C, it exhibits an extremely low temperature hysteresis of less than ±0.05 ppm, ensuring precise clock signals even in a variety of extreme environmental conditions. This exceptional precision and stability are critical for aerospace equipment, guaranteeing synchronization and consistency in navigation, communication, and control systems.
2. Wide frequency range
It supports a frequency range from 10 MHz to 100 MHz, meeting the needs of various aerospace devices. Its flexible frequency support makes it suitable for a wide range of applications, including navigation systems, communication equipment, and data processing systems.
3. Anti-interference capability
The satellite communication environment is extremely harsh, typically requiring quartz crystal oscillators that are resistant to interference and have low noise levels. To enhance their performance, manufacturers employ advanced packaging techniques and incorporate anti-interference measures such as metal shielding layers. At the same time, the internal circuit design of the crystal oscillator is optimized to bolster its resistance to interference. These measures enable the crystal oscillator to maintain a stable frequency output even in complex environments, thereby ensuring the reliable operation of satellite receiving systems.
4. Small-size package
It features a compact 2.0mm x 1.6mm package, making it ideal for integration into devices with limited space. Its small size provides greater flexibility in device design, helping to achieve miniaturization and lightweighting—key considerations in aerospace equipment design.
5. Low-power design
It supports a wide voltage input range from 1.8V to 3.3V and features a low-power design that significantly reduces power consumption. This low power consumption not only extends the device’s service life but also decreases reliance on power resources—both of which are critical characteristics for aerospace missions.
6. Long-term Reliability
The frequency aging rate is as low as ±1×10⁻⁶ per year, ensuring high accuracy even over long-term operation and meeting the durability requirements of industrial-grade equipment.
As space exploration, deep-sea research, polar scientific expeditions, and other activities continue to deepen, the demand for crystal oscillators capable of withstanding extreme environments is steadily growing. In the future, crystal oscillator technology will achieve even greater innovations in adapting to environments characterized by extreme temperatures, high pressures, and intense radiation. The rapid advancement of emerging technologies such as artificial intelligence, the Internet of Things, and quantum computing will also bring new opportunities for enhancing the frequency stability of crystal oscillators. Looking ahead, with the continuous progress of science and technology, TKD crystal oscillator frequency stability technology will keep evolving toward higher precision, stronger environmental adaptability, and deeper integration with emerging technologies, providing solid support for driving technological innovation and industrial upgrading across various fields.
