Crystal oscillator selection guide

In the era of the Internet of Things, we increasingly urgently need accurate and stable clock signals and sophisticated devices. This makes crystal oscillators ((full name crystal oscillator, is a tiny electronic component based on quartz crystals, can generate a highly accurate and stable oscillation signal, this accurate and stable clock signal is not only used for synchronous data transmission, but also in a variety of applications to ensure that the device works together, so that the entire circuit system can run orderly and accurately.))widely applicable in fields that require high-precision clocks, such as communication, power grids, aviation, navigation and positioning, radar, etc.

As a leading enterprise in the field of time and frequency research, California Triangle has developed medium and high-end crystal OCXO products with complete features, leading performance, conforming to industry standards and supporting customization according to the needs of different scenarios to meet customer needs.

With the rapid development of 5G communication technology and the Internet of Things, crystal vibration has been widely used in the field of communication by providing high-precision clock signals for devices to ensure synchronous data transmission. As a key component in the communication system, the performance of crystal oscillator is directly related to the data transmission rate and the overall communication quality of the communication system. Therefore, the complexity of the communication system requires the crystal oscillator to provide a highly precise frequency to ensure that the individual devices work together on a synchronous basis. In addition, characteristics such as high stability and wide operating temperature range are also key requirements for crystal oscillators in the field of communication.

In order to meet the needs of crystal oscillator in complex communication application scenarios, on the basis of providing high precision frequency, California Triangle has developed ultra-stable OCXO O3627, which has the highest temperature stability in the same class in the 5E-11 industry, second stability is better than 5E-12 performance, and a series of high-end crystal oscillator products with high support for -55℃~+85℃ wide temperature and high cost performance. At the same time, for the scene with high punctuality and accuracy requirements, SYce clock module products can support the maximum maintenance ability of 1.5us@24 hours for users to choose.

In the field of power grid, the high-precision clock signal of crystal oscillator plays a vital role in energy metering, synchronous transmission, monitoring system, etc., which can ensure the stable and reliable operation of the power network. In smart grids, crystal supports data transmission and control systems that facilitate coordinated operations among power equipment for more efficient and intelligent power management and distribution.

The special place in the power grid scenario is that the power system equipment often works under extreme environmental conditions such as strong magnetic field, strong electric field, and high temperature. This also means that the power grid requires that the crystal oscillator at high temperature has characteristics such as electromagnetic interference resistance and high temperature stability, and needs to pass a special electromagnetic compatibility test. In addition, the miniaturized and superimposed crystal vibration with the smallest size and volume is also another trend in the demand for crystal vibration in the power grid field.

In order to meet the strict requirements of crystal vibration for power grid application scenarios, California Triangle's R team has developed small volume and high-performance crystal vibration products that support low -55℃ and high +95℃ wide temperature, with ultra-high stability and operating frequency range of 5 ~ 100MHz through independent experimental testing.

In addition, based on the autonomous and controllable high-stability OCXO technology and the ability to hold algorithms, California Triangle has developed clock modules with high hold ability, ultra-high frequency stability, and ultra-low phase noise for multi-field scenarios, providing ideal solutions for servers, cellular networks, time cards, test equipment, and punctuality modules.

TCXO achieves high precision frequency output through temperature compensation circuit, and California Triangle realizes high stability and low noise TCXO products with -170dBc/Hz background noise, -40~85℃ 0.05ppm, up to 200MHz through independent technology, which has been widely used in communication, industrial control, instrumentation, electronic consumption and other fields.
