Microchip Technology PL460 Programmable Narrow-Band PLC Modems

Microchip Technology PL460 Programmable Narrow-Band PLC Modems are built to run any PLC protocol in a frequency band below 500kHz. The PL460 embeds the PLC line driver, allowing a highly integrated solution that reduces the total bill of materials, simplifies the layout, and eases modem design.

The Microchip PL460 PLC Modems comply with FCC, ARIB, KN60, and CENELEC EN50065 regulations matching requirements of the Internet of Things (IoT) and Smart Energy applications. The device supports state-of-the-art narrowband PLC standards such as ITU G.9903 (G3-PLC^®), ITU G.9904 (PRIME) as well as any other narrowband PLC protocols, at the same time being a future-proof platform able to support the evolution of these standards.

The PL460 is intended to be driven by external Microchip host devices, thus delivering additional flexibility on the host side. The Microchip host device loads the appropriate PLC-protocol firmware in the PL460 before modem operation and controls the PL460 modem.
