MAX2990ECB+

Telecom Overview

The MAX2990ECB+ is a power line communication (PLC) baseband modem designed for half-duplex asynchronous data transmission over AC power lines. It integrates the physical layer (PHY) and media access control (MAC) using a 16-bit MAXQ microcontroller core with 32kB password-protected flash, 5.12kB ROM, and 8kB SRAM. The device supports OFDM modulation with speeds up to 32kbps in the 10kHz–95kHz range and 100kbps in the 10kHz–490kHz range. It complies with CENELEC A/B/C, FCC, and ARIB standards, featuring DES encryption, CRC16/32, FEC, and jammer cancellation. Operating voltage ranges from 2.7V to 5.5V, with an extended temperature range of -40°C to +85°C in a 64-pin LQFP package.
