European satellite and STMicroelectronics release low-cost, low-power interactive satellite terminal system chips

One of the world's largest satellite communications operators, Eurostar (NYSE and Paris Stock Exchange: ETL) and STMicroelectronics, the world's leading MEMS supplier across multiple electronic applications, the world's leading semiconductor supplier STMicroelectronics, ST for short; New York Stock Exchange (STM) code: STM announces significant results in the development of next-generation satellite chips, which will be used in European satellites' SmartLNB interactive satellite terminals.

The advent of the technologically advanced STMicroelectronics low-power system chip (STiD337) will significantly reduce the overall cost of interactive satellite terminals. The European satellite's SmartLNB satellite terminal is the first application of the STiD337, which helps reduce satellite terminal costs, upgrade satellite services, and significantly reduce power consumption.

The SmartLNB satellite terminal is an electronic antenna feed that replaces the traditional DTH satellite signal Ku-band receiving unit. It embeds one or more tuner/demodulators directly in the high-frequency head (LNB) and adds one for IP packet optimization. Narrowband loop. The SmartLNB terminal enables a variety of Internet TV applications, providing a transparent, bi-directional IP link compatible with existing services. The target application is not limited to the TV broadcasting market, but also covers the sudden emergence of the connected equipment market (machine-to-machine communication, Internet of Things, SCADA, home automation, intelligent buildings, etc.), which is a cost-effective satellite solution.

STMicroelectronics also uses its ultra-low power 28nm FD-SOI (fully depleted silicon-on-insulator) manufacturing process for deep sleep and automatic wake-up. The full-speed operation mode has a maximum power dissipation of 3.5W and a sleep mode (typically dissipated power) of less than 50mW, making the STiD337 the most energy-efficient satellite system chip on the market, which can improve the performance and energy efficiency of the SmartLNB to a new level.

STiD337 adds the latest DVB-S2X satellite forward link standard and GSE (Universal Stream Encapsulation) efficient data processing standard with data throughput of over 100Mb/sec. The loop implements a software radio method optimized for broadband technology with the typical asynchronous access capability of the SmartLNB tuner. The chip also includes all the supporting hardware for real-time multiple access. The loop modulation operation is the responsibility of the internal processor. The platform includes an ARM® Cortex®-A9 dual-core processor with a built-in NEONTM coprocessor and four ST231 DSP Offload coprocessors to increase computing power and ensure high flexibility in loop modulation options.
