A millimeter-sized chip
Seemingly inconspicuous
In fact, “ability to reach the sky”
Nanjing Xingsi Semiconductor Co., Ltd., located in the Research and Innovation Park of Jiangbei New District, recently successfully lit up its self-developed satellite baseband chip CS7620 and completed the first high-definition video call test, realizing end-to-end verification of the mobile phone direct satellite connection solution.
“This is the company’s
A major breakthrough in the field of direct mobile phone connection to satellites.
We have also become the only two
Chip-Level Solutions
The team that links with low-orbit broadband satellites,
Transmit ground, sky and space communication signals
Interconnected,
Even on the plane,
You can surf the Internet even in the ocean.”
Xu Xin, head of R&D at Starthink Semiconductor, said, “This also marks a further step towards the commercialization of the company’s chips. Next year, we will be able to see terminal devices using this chip on the market.”
In the past, satellite phone charges were high and the scope of use was narrow, which was very far away from ordinary users. With the continuous upgrading of mobile phone functions, satellite communication has almost become one of the “entry barriers” for high-end smartphones. At the beginning of this year, the Ministry of Industry and Information Technology and seven other departments jointly issued the “Implementation Opinions on Promoting the Innovation and Development of Future Industries”, which mentioned strengthening forward-looking planning and deployment of future information and promoting the industrialization and application of satellite Internet.
It is understood that satellite Internet is based on satellite communication technology to access the Internet, which is like moving ground base stations into space, and each satellite is a mobile base station.
“The initial satellite calls were a bit similar to the 2G era, and then Beidou short messages appeared, which carried text and pictures in a form similar to SMS and MMS. This time we used low-orbit broadband satellite technology, with uplink and downlink rates exceeding 100Mbps. We can use traffic to surf the Internet, transmit high-definition pictures, and even make video calls. The basis for the realization of these functions is that we have made significant improvements in the working bandwidth and transmission rate of the chip.” Xu Xin said.
Make phone calls, send WeChat messages, watch videos…
When we use mobile phones
Baseband chip responsible for communication functions
It is playing a big role
It is worth noting that due to the company’s evolution in 5G communication technology, in addition to satellite communications, this satellite baseband chip can also access ground-based LTE base stations and 5G base stations, supporting a variety of terminal forms and application scenarios such as mobile phones directly connected to satellites, satellite broadband access, satellite Internet of Things, industrial Internet, wearable watches, feature phones, etc.

“At present, we are cooperating with leading mobile phone manufacturers, satellite terminal manufacturers, module manufacturers and MBB (mobile broadband) manufacturers in the industry, and plan to launch terminal products based on the CS7620 chip in 2025. The next critical task is the technical integration of the satellite into space. We have arranged staff to carry out the final integration work before the satellite launch.” Xu Xin said that in the next step, he will also lead the team to conduct relevant national laboratory certification and operator certification for this chip, obtain a network access license, and accelerate the realization of commercial applications.
