OFDM-based modem delivers up to 100-kbit/s at 10- to 490-kHz

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX2990, a power-line communication (PLC) modem based on the OFDM (orthogonal frequency division multiplexing) method.

This device employs advanced broadband-communication techniques to deliver cost-effective, two-way data communication over AC and DC powerlines at speeds up to 100-kbit/s. By using existing powerlines, it reduces the need for external cables to interconnect between network nodes.

Supporting a 10-kHz to 490-kHz frequency range, the MAX2990 complies with international power-line signaling regulations, including CENELEC, FCC, and ARIB. The MAX2990 is intended for applications requiring high data rates over long distances, such as automatic meter reading (AMR); energy management and load control; lighting control; and building, industrial, and home automation.

The MAX2990 is available in a 64-pin LQFP package and is fully specified over the -40°C to +85°C extended temperature range.

Pricing starts at $8.50 (1000-up, FOB USA).
Availability: Now.
Datasheet: MAX2990.
