MAX2982

Industrial Broadband Powerline Modem

General Description

Features

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 phys-

ical (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 HomePlugM 1.0 Powerline Alliance

Specification.

The MAX2982 offers reliable broadband communication

for industrial environments. The PHY layer comprises an

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: DBPSK,

DQPSK (1/2 rate FEC), DQPSK (3/4 rate FEC), and ROBO.

The MAX2982 offers -1dB SNR performance in ROBO

mode, a robust mode of operation, to maintain commu-

nication 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-Sâ¢ microprocessor allowing feature enhance-

ment, worldwide regulatory compliance, and improved

testability. Optional spectral shaping and notching pro-

files provide an unparalleled level of flexibility in system

design. Additionally, the automatic channel adaptation

and interference rejection features of the MAX2982 guar-

antee outstanding performance. Privacy is provided by a

hard-macro DES encryption with key management.

The MAX2982 supports an IEEEÂ® 802.3 standard Media

Independent Interface (MII), Reduced Media Independent

Interface (RMII), synchronous FIFO supporting a glue-

free interface to microcontrollers, USB1.1, and 10/100

Ethernet MAC. These interfaces and standards compli-

ance simplify configuration of monitoring and control

networks. Fast response time and an integrated tempera-

ture sensor make the MAX2982 an excellent solution for

real-time control over power lines. The MAX2982 operates

over the -40NC to +105NC temperature range and is avail-

able in a 128-pin, lead-free, LQFP package.
