MAX2982
Industrial Broadband Power-Line Modem
General Description
The MAX2982 power-line transceiver utilizes state-of-
the-art CMOS design techniques to deliver the highest
level of performance, flexibility, and operational tem-
perature 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 power-line com-
munication solution fully compliant with HomePlugM 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 con-
ditions. 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, 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
-40NC to +105NC temperature range and is available in a
128-pin, lead-free, LQFP package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
