GRAND

GRAND was founded by a group of returning PhDs. GRAND is a high-tech company dedicated to the research, development, and sales of high-performance, high-quality RF, analog, and mixed-signal integrated circuits. The core team members of GRAND have over 20 years of experience in research and mass production. They have previously worked for leading international semiconductor companies such as Qualcomm, Broadcom, and Avago Technologies, and have the capability to independently develop advanced chips. Through our collective efforts, we have successfully developed and mass-produced a variety of chip products, including high-performance phase-locked loop chips, high-speed switches, and power management chips. Our phase-locked loop chips have achieved world-leading levels in output jitter and loop bandwidth, meeting the application requirements for high-speed interface clocks and system reference clocks in various fields. Our products are widely used in areas such as wired communication (switches and routers), wireless communication (base stations and small cells), radar, instrumentation, aerospace, precision measurement, smart homes, and consumer electronics. Due to the low self-sufficiency rate of chips in China and the strong dependence on foreign manufacturers, our clock chips, being high-performance clock generation and calibration chips, play a critical role in achieving 5G clock synchronization and improving time accuracy. In the coming years, with the construction of 5G micro base stations, the demand for PLL chips will continue to grow.
