二、 Application scenarios of SG-8200CJ in communication equipment

1. Mobile communication base station

In the large and complex communication hub of mobile communication base stations, the baseband processing unit of the base station is responsible for complex operations such as encoding, decoding, modulation, and demodulation of a large amount of communication data. The SG-8200CJ, with its wide frequency range, can accurately provide adaptive clock signals for the baseband processing unit, ensuring the accuracy and efficiency of data processing. It can achieve a frequency tolerance of ± 15 × 10 ⁻⁶ within the temperature range of -40 ° C to+105 ° C. Even under various complex environmental temperature changes in the base station, it can stably output accurate frequencies and avoid signal processing errors caused by frequency deviation. In the RF transceiver module, the low jitter characteristics of the crystal oscillator (such as phase jitter as low as 1.1ps at a frequency of 125MHz) ensure high-quality transmission and reception of RF signals. In 5G base stations, high-speed data transmission and multi antenna technology require extremely high clock synchronization. The SG-8200CJ can meet the strict clock synchronization requirements between different modules in the base station, effectively improve communication quality, and ensure smooth and stable communication for users within the coverage area of the base station. Whether it is high-definition video calls, large file transfers, or low latency real-time interactive applications, it cannot do without its stable and accurate clock support.

2、 Network switches and routers

Network switches and routers are key nodes in data transmission networks, and fast and accurate forwarding of data is their core function. The SG-8200CJ programmable crystal oscillator provides a stable clock reference for the data processing chips in these devices. In switches, facing massive data traffic, the high-precision frequency output of crystal oscillators enables the switch to accurately process data from different ports according to time slices, ensuring fast and error free data exchange. Its power supply voltage range is 1.62V to 3.63V, which can adapt to various power supply environments inside the switch and ensure stable operation of the equipment. In the router, reliable clock signals provided by SG-8200CJ ensure the timeliness and accuracy of operations such as querying, updating routing tables, and packet forwarding decisions.

3、 Accurate timing clock source for optical communication module

In optical communication systems, the optical transmitter and receiver need to accurately convert electrical signals into optical signals for long-distance transmission. SG-8200CJ provides a stable clock signal to ensure that the sampling, encoding, and modulation processes of electrical signals are strictly carried out in chronological order, ensuring the quality and transmission accuracy of optical signals. At the optical receiver end, the stable clock of the crystal oscillator helps to accurately demodulate, decode, and recover weak optical signals. In high-speed optical communication links, the low jitter characteristics of SG-8200CJ effectively reduce the bit error rate during signal transmission, improving the reliability and transmission distance of optical communication systems.

4、 Miniaturization and multifunctionality of communication equipment

With the development of communication technology, communication devices are constantly evolving towards miniaturization and multifunctionality. The miniaturization package (2.0 × 1.6mm) of SG-8200CJ programmable crystal oscillator provides strong support for this trend. In devices such as smartphones and portable wireless routers, their compact size allows for easy layout within limited circuit board space, freeing up more space for other functional modules and contributing to the lightweight design of the devices. Meanwhile, its programmability enables the same type of crystal oscillator to meet the diverse clock frequency requirements of different communication functions. For example, in smartphones, suitable clocks can be provided for communication baseband chips, as well as precise clock signals for wireless modules such as Wi Fi and Bluetooth, achieving the integration and collaborative work of multiple communication functions, improving the overall performance and user experience of communication devices, and adapting to modern people's demand for convenient and efficient communication devices.
