MLKHN1500 Single Chip IEEE 1901
Compliant HD-PLC


MLKHN1500 is the world’s first fully compliant IEEE 1901 HD-PLC Power line Communications (PLC) solution delivering bi-directional, IP based, high-speed communication over AC/DC power lines, COAX and twisted pair wiring, where wider bandwidths, robustness, long-range, support for larger number of nodes, and highly secure network is required.

The MLKHN1500 combines the Physical (PHY), Media-Access-Control (MAC), 128Mb SDRAM, and a fully integrated Analog-Front-End (AFE) with high precision A/D, D/A data converters and programmable gain amplifiers (PGA) in a single compact package. The modem is based on an Orthogonal Frequency Division Multiplexing (OFDM), using advanced Forward-Error-Correction (FEC) techniques to allow the most robust data communication over poor channels, especially in environments with high implosive noise such as the harsh AC power lines. Security is provided by an 128-bit AES encryption engine meeting today’s Internet-of-Things (IoT) requirements.

Evaluation boards, reference design, Software Development Kits (SDK) and Hardware Development Kits (HDK) are now available to help speed up your evaluation and development projects.
