PL460
PL460 Data Sheet
Description
The PL460 is a programmable modem for narrow-band Power Line Communication (PLC), able to run any PLC
protocol in the frequency band below 500 kHz. PL460 embeds the PLC line driver, providing a highly integrated
solution that reduces the total bill of materials, simplifies the layout and eases the modem design.
This device has been designed to comply with FCC, ARIB, KN60 and CENELEC EN50065 regulations matching
requirements of the Internet of Things and Smart Energy applications. It supports state-of-the-art narrow-band 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 designed to be driven by external Microchip host devices, thus providing an additional level of flexibility
on the host side. The Microchip host device loads the proper PLC-protocol firmware in the PL460 before modem
operation and controls the PL460 modem.
