HD-PLC Conforms to IEEE 1901 -2020 standard

High Definition Power Line Communication (HD-PLC) is a wired communication technology that supports communication networks by overlaying high frequency signals (2~28MHz) on existing power lines, telephone lines, cables twisted pair coaxial and other type of wire. In 2021, the 4th generation of HD-PLC was published in the IEEE 1901-2020 standard specifying 1/2 and 1/4 transmission modes to enable longer distance communications. It is capable of facilitating a communication or network up to a range of 10 km when combined with multi-hop technology. With these new features, this advanced HD-PLC solution is expected to be more widely adopted in many different fields and new application areas.

SC1320A Features and Specifications

The SC1320A is the first LSI in the world to adopt the 4th generation HD-PLC *1 with an IP core conforming to the IEEE 1901-2020 standard licensed from Panasonic Holdings Corporation. Socionext’s strength in advanced circuit design and analog signal processing interface technology enables the implementation of the HD-PLC4 specification and features on the SC1320A while maintaining ultra-low power consumption ( 200mW). It uses only a single 3.3V power supply and comes in a compact 7 x 7mm package. This solution features built-in I/O such as SPI/UART and Ethernet MAC (RMII), allowing the SC1320A to be easily integrated into home appliances, HEMS and IoT products.

Future development

Socionext has developed a radar sensor*2 with built-in high-level detection of a person’s position and motion, and SC1330A*3, a low-power, low-cost, LPWAN 2.0-enabled LSI for IoT beacons. Socionext believes that combining these solutions with the SC1320A LSI can bring more value to IoT and smart connected systems and devices. For example, a high sensitivity presence detection radar sensor can be used in a complete hybrid communication network incorporating both the SC1320A and the SC1330A.

The small-size, low-power LSI SC1320A HD-PLC helps companies develop high-end products at lower cost. Socionext will continue to take advantage of the 4e generation of HD-PLC advantages and functionalities to create new technologies, new values ​​and contribute to the future of society 5.0.
