5G communication, radar electronic countermeasures, instruments and other preferred weapon-CT ultra-low noise, high second stable OCXO

If the CPU is the "strongest brain" in charge of the digital circuit of electronic products, then the crystal oscillator is like the "heart" to provide continuous blood circulation for the whole body, not only to provide a stable clock signal for the CPU, but also to control the "beat" of the circuit with its precise frequency to ensure the orderly operation of each circuit module.

Without the precise adjustment of the crystal oscillator, the entire system will not be able to maintain synchronization, resulting in data loss or processing errors. Therefore, choosing the right crystal oscillator is crucial to optimize circuit design and improve product performance and reliability.

With the vigorous development of 5G communication, radar electronic countermeasures, satellite navigation, instrumentation and other key areas of society , the market demand for crystal vibration is also developing in the direction of ultra-low phase noise, high stability, low power consumption, miniaturization, and high-frequency. At this time, the Oven Controlled Crystal Oscillator (OCXO) came into being, As a quartz material oscillator on the market as a frequency source of the solution with the highest accuracy, with its low phase noise, small size and other characteristics to become the first choice in many high-demand digital circuits, top frequency source.

Industry good, low phase noise constant temperature crystal vibration into "Xiangbobo"?

Benefiting from the favorable development of 5G communication, radar electronic countermeasures, satellite navigation, instrumentation and other industries, the market demand for crystal vibration products remains high. According to the statistics and forecast of QYR, the global crystal market sales in 2023 reached 34.77 billion yuan, and it is expected to reach 50.912 billion yuan in 2030, with a compound annual growth rate (CAGR) of 5.7% (2024-2030), and the global crystal market potential is immeasurable.

As an important index to evaluate signal sources, phase noise plays a crucial role in communication systems, radar systems, satellite navigation systems and precision measurement, which need to reduce signal interference by reducing phase noise to improve the signal quality and reliability of the system.

In the field of communication: in the 5G/6G wireless communication system with high frequency and high data rate, phase noise may cause serious distortion and distortion of the signal, resulting in data transmission errors and timing offset, thereby reducing the reliability and effectiveness of communication.

Satellite navigation: GPS, GNSS and other satellite navigation systems, highly dependent on accurate radio frequency signal transmission and reception, low phase noise oscillator can provide a more stable carrier signal, which is directly related to positioning accuracy and navigation stability.

Instrumentation field: Instrumentation as a test source, often need to have a higher accuracy than the measured signal, is a hard indicator of many measuring instruments. Good phase noise is directly related to the measuring ability of the instrument.

Radar electronic warfare field: Radar emits pulses at a specific frequency and measures the change in frequency of each return pulse. Phase noise will worsen the Doppler shift information, if the LO phase noise of the whole is poor, it will cause the weak echo signal of some targets to be submerged in the side band of the strong echo signal and can not be detected normally, and then affect the detection of target distance, speed and direction information.

The Doppler signal is shielded by clutter

This is why constant temperature crystal oscillator (OCXO), as a core component with low phase noise characteristics and high precision frequency source, has become "popular" in areas with high requirements for phase noise.

In order to meet the needs of low phase noise and domestic constant temperature crystal oscillator, the localized, ultra-low noise and high second stability OCXO solution developed by California Triangle can be mass-produced to achieve phase noise ≤-122dBc@1Hz, second stability ≤1.5E-13, and temperature stability is better than 0.5ppb@-40~85℃. The actual measurement can reach -123.5dBc@1Hz, 9.06E-14/1s, which has the highest international standard.

At the same time, in addition to the constant temperature crystal oscillator products, customized clock products such as phase-locked crystal oscillator, tame crystal oscillator, and multi-output have been developed, and a complete clock signal chain ecosystem has been built step by step. It can provide a complete clock signal solution with localization, low phase noise, high stability, low power consumption, miniaturization, high frequency and other characteristics for different customers in different fields.

Keeping up with the market vane, California Triangle will continue to dig for thousands of industries with lower phase noise, lower power consumption, higher stability, smaller package and higher frequency clock products with strong self-research capabilities.

In the future, California Triangle will continue to develop pain points based on customer demand, deepen reform, strive to open up the blocked points that restrict the development of time-frequency new quality productivity, establish a high standard time-frequency industry chain integration system, innovate the ecological integration of production factors, provide the society with higher quality end-to-end time-frequency synchronous solutions, empower industry customers, and build new potential energy for the development of new quality productivity.
