Industrial Broadband Powerline Modem

The MAX2982 powerline transceiver utilizes state-of-the-art CMOS design techniques to deliver the highest level of performance, flexibility, and operational temperature range at reduced cost. This highly integrated design combines the Media Access Control (MAC) and the Physical (PHY) layers in a single device. The MAX2982 digital baseband and its companion device, the MAX2981 analog front-end (AFE) with integrated line driver, offer a complete high-speed powerline communication solution fully compliant with HomePlug® 1.0 Powerline Alliance Specification.

The MAX2982 offers reliable broadband communication for industrial environments. The PHY layer is comprised of 84-carrier OFDM modulation engine and Forward Error Correcting (FEC) blocks. The OFDM engine can modulate the signals in one of four modes of operation, namely DBPSK, DQPSK (1/2 rate FEC), DQPSK (3/4 rate FEC) and the ROBO mode. The MAX2982 offers -1dB SNR performance in ROBO mode, a robust mode of operation, to maintain communication over harsh industrial line conditions. Additionally, advanced narrow-band interference rejection circuitry provides immunity from jammer signals.

The MAX2982 offers extensive flexibility by integrating an ARM946E-S™ microprocessor allowing feature enhancement, worldwide regulatory compliance, and improved testability. Optional spectral shaping and notching profiles provide an unparalleled level of flexibility in system design. Additionally, the automatic channel adaptation and interference rejection features of the MAX2982 guarantee outstanding performance. Privacy is provided by a hard-macro DES encryption with key management.

The MAX2982 supports an IEEE® 802.3 standard Media Independent Interface (MII), Reduced Media Independent Interface (RMII), synchronous FIFO supporting a glue-free interface to microcontrollers, and 10/100 Ethernet MAC. These interfaces and standards compliance simplify configuration of monitoring and control networks. Fast response time and an integrated temperature sensor make the MAX2982 an excellent solution for real-time control over power lines. The MAX2982 operates over the -40°C to +105°C temperature range and is available in a 128-pin, lead-free, LQFP package.
