General Description

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 HomePlug

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-S™ 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 IEEE

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.
