O2525 constant temperature crystal oscillator 10M (12v/-40~85 ℃/5ppb)

With the vigorous development of key social fields such as 5G communication, radar electronic countermeasures, satellite navigation, and instrumentation, and under the guidance of national independent and controllable policies, the market demand for crystal oscillators is also moving towards localization, ultra-low phase noise, high stability, low power consumption, miniaturization, and high frequency. At this time, the Constant Temperature Crystal Oscillator (OCXO) emerged, also known as the Constant Temperature Crystal Oscillator, OCXO)， As the most accurate solution in the current market that uses quartz material oscillators as frequency sources, it has become a powerful tool and top-level frequency source in many high demand digital circuits due to its low phase noise, small size, and other characteristics.

5G communication, radar electronic countermeasures, instrumentation and other industries

Good news for the industry, low phase noise constant temperature crystal oscillator becomes a "hot commodity"?

Benefiting from the favorable development of industries such as 5G communication, radar electronic countermeasures, satellite navigation, and instrumentation, the demand for crystal oscillator products in the market remains high. According to statistics and predictions from QYR (Hengzhou Bozhi), the global crystal oscillator market sales reached 34.77 billion yuan in 2023, and are expected to reach 50.912 billion yuan by 2030, with a compound annual growth rate (CAGR) of 5.7% (2024-2030). The potential of the global crystal oscillator market is incalculable.

As an important indicator for evaluating signal sources, phase noise plays a crucial role in reducing signal interference and improving signal quality and reliability in communication systems, radar systems, satellite navigation systems, and precision measurements.

In the field of communication: In high-frequency, high data rate 5G/6G wireless communication systems, phase noise may cause severe distortion and distortion of signals, leading to data transmission errors and timing offsets, thereby reducing the reliability and effectiveness of communication.

In the field of satellite navigation, satellite navigation systems such as GPS and Beidou rely heavily on precise RF signal transmission and reception. Low phase noise oscillators can provide more stable carrier signals, which directly affects positioning accuracy and navigation stability.

In the field of instrumentation: As a testing source, instrumentation often requires higher accuracy than the measured signal, which is a hard indicator for many measuring instruments. Good phase noise directly affects the testing capability of the instrument.

In the field of radar electronic countermeasures, radar emits pulses at a specific frequency and measures the frequency variation of each returned pulse. Phase noise can deteriorate the information of Doppler frequency shift. If the LO phase noise of the whole machine is poor, it will cause weak echo signals of some targets to be submerged in the sidebands of strong echo signals and cannot be detected normally, thereby affecting the detection of target distance, velocity, direction and other information.

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

Saisi localization, ultra-low noiseHigh second stability solution

The crystal oscillator industry in our country started late, and constant temperature crystal oscillators still heavily rely on imports. Faced with the rapid development in various key fields and the guidance of independent and controllable policies in national key fields, the wave of domestication of constant temperature crystal oscillators has arrived.

To meet the requirements of low phase noise and domestically produced constant temperature crystal oscillators, Saisi's self-developed domestically produced, ultra-low noise, high second stability OCXO solution can achieve mass production of ≤ -122dBc@1Hz The phase noise, second stability of ≤ 1.5E-13 level, and temperature stability are better than 0.5ppb@-40 ~85 ℃. Actual measurement can achieve -123.5dBc@1Hz 、 9.06E-14/1s。

At the same time, in addition to constant temperature crystal oscillator products, customized clock products such as phase-locked crystal oscillators, tamed crystal oscillators, and multi-channel outputs have also been developed, gradually building a complete clock signal chain ecosystem. We can provide complete industry clock signal solutions with features such as localization, low phase noise, high stability, low power consumption, miniaturization, and high frequency for different fields and customers.
