Dapu firstly launched the next generation of clock solutions
One of the world"s largest ICT exhibition, and the largest and the most influential world-class exhibition of information communication in Asia ---- PT/EXPO COMM CHINA was held in Beijing International Exhibition Center from 26th to 30th September 2011. The exhibition focused on “the new generation of information technology” and the latest achievements of Triple Play. Dapu, as the supplier of the “core electronics high-end universal chip and fundamental software products” and technology solutions, brought 6 series of products and firstly launched TD-LTE and IEEE1588V2 clock products and solutions for the exhibition. On the afternoon of 28th September, Member of the Political Bureau of CPC Central Committee and Vice-Premier of the State Council Dejiang Zhang, accompanied by Minister of Ministry of Industry and Information Technology Yu Miao, Director of the Administration of Radio, Film and Television Fuchao Cai etc., had visited the Dapu’s booth and gave some guidance. He thought highly of the achievements of the clock technology innovation created by Dapu, and encouraged Dapu to launch more “core electronics high-end universal chip and fundamental software products” and contribute to the development of “the new generation of information technology”.







On the exhibition, Dapu Telecom launched the most competitive GPS/Beidou dual-mode timing module and clock compensation chip with high compensation ability, which has filled in the home gaps of China.And, Dapu also launched the products and solutions which can meet the requirements of TD-LTE and IEEE158V2, including CM55F with the holdover of 1.5uS/24hrs, high stable O23Band strong stratum 3 TCXO---T75B. These new products had been highly paid attention by abroad and domestic communication equipment manufacturers. After fully knowing the innovation platform, core technology and core products of Dapu, and understanding the design philosophy “continue reducing the dependence on the physical environment”, the leaders of communication equipment manufacturers had recognized the high stable, high holdover and ultra small size crystal oscillators and clock modules, and want to further cooperate with Dapu.
 
Any communication equipment needs the operating frequency from the clocks. Clock performance is important to the equipment performance, so the clock is generally called the “heart”of the equipments. High precise time benchmark has been the guarantee platform of the communication base station, power grid, radio and television, security and protection monitoring, industrial control and military industry etc. Early GSM and CDMA network of China, as lack of clock technology without independent intellectual property rights, it had happened that the network broken down because GPS didn’t provide the time service then the clock loses the lock. Information security and network security and reliability had been always troubling the communication system. Then, new generation of broadband mobile communication technology---TD-SCDMA and TD-LTE were launched, which can support Beidou and GPS dual-mode timing service system, so that the potential risk lying in the mobile communication network had been eliminated largely. Since established, adhering to the tenet of “changing the status quo of Chinese high end clock frequency components replying on the imports”, by the constant innovation, Dapu Telecom has developed the proprietary chip with the independent intellectual property right. The chip can achieve 500 times optimization, it is the only clock compensation chip in China and beyond other International brands. With the algorithm and chip researched for many years, Dapu has developed the smallest SMD stratum 3E, GPS/Beidou module which can replace the atomic clock, new generation of network clock based on TD-LTE and 1588 protocol. During these years, Dapu is always focusing on the research on the high stable crystal oscillators and clock technology, working hard for the basis materials, fundamental science, electronics application, algorithm, automation equipments and chips etc., and providing the Chinese even global customers more matched crystal oscillators in the application of communication and industrial control.
 
In the future, Dapu will go along the development trend of the next generation of clock technology, by the platform of technology center and key labs, positively cooperate with the university and upstream and downstream firms, continues to go beyond itself and launches leading-edge products.
