The MAX2990 power line communication (PLC) base-

band modem delivers a cost-effective, reliable, half-

duplex asynchronous data communication over AC

power lines at speeds up to 100kbps. The MAX2990 is

a highly integrated system-on-chip (SoC) that combines

the physical (PHY) and media access control (MAC)

layers using Maxim’s 16-bit MAXQ microcontroller core.

The MAX2990 utilizes OFDM modulation techniques to

enable robust data communication using the same

electrical network that supplies power to all other

devices on the network.

The MAX2990 includes the MAXQ microcontroller core.

The MAXQ is a 16-bit RISC microcontroller with 32kB flash

memory, 5.12kB of ROM, and 8kB SRAM, of which 4kB

that can be simultaneously accessed by the MCU and the

PHY. The MAX2990 is integrated with modules for serial

communication (SPI™, I

(RTC) for time stamping, in addition to standard blocks

such as timers, GPIO, and external interrupts.

The MAX2990 transceiver is based on an orthogonal

frequency division multiplexing (OFDM) technique that

allows robust data transmission over poor channel con-

ditions specifically for environments with impulsive

noise. OFDM with binary phase shift key (BPSK) and

forward error correcting (FEC) blocks are used

because of their inherent adaptability in the presence of

frequency selective channels without the use of equal-

izers, resilience to jammer signals, robust communica-

tions in the presence of group delay spread, and

robustness to impulsive noise. The MAX2990 features

jammer cancellation that removes constant sinusoidal

interference signals for FCC and ARIB bands. Privacy

is provided by DES encryption.

The MAX2990 is available in a 64-pin LQFP package

and is specified over the -40°C to +85°C extended tem-

perature range.
