Wired

Wired connectivity solutions are inherently secure and reliable. They are popular in building automation, smart meters, smart energy control, smart lighting, industrial, security, and other Internet-of-Things (IoT) applications. ON Semiconductor offers a broad portfolio of certified and robust wired transceivers and System-on-Chip (SoC) solutions, supporting KNX, Narrowband PLC (Power Line Communication), M-BUS, HART, and PoE-PD (Power Over Ethernet). The KNX and PoE-PD devices include integrated DC-DC converters.

M-BUS Design Changes Between TSS721A and NCN5150
NCN5150 is a drop in replacement of the TSS721A for all designs using a VDD capacitor larger than 1 F. The NCN5150 M−BUS transceiver (in SOIC version) is pin−to−pin compatible with the TSS721A from Texas Instruments™ and can replace this component with no changes to the PCB layout on a typical implementation.

Mains Synchronization for PLC Modems
The sensitivity of a communication receiver strongly depends on a correct and reliable synchronization with the transmitter. In power line communication (PLC), the zero crossing of the mains is commonly used for this synchronization.
