MAX2991

Power-Line Communications (PLC) Integrated

Analog Front-End Transceiver

General Description

Features

S Optimized to Operate with the MAX2990 PLC

The MAX2991 power-line communication analog front-

end (AFE) is a state-of-the-art integrated circuit that

delivers high integration and superb performance, while

reducing the total system cost. The MAX2991 is the first

AFE specifically designed for OFDM (orthogonal fre-

quency division multiplexing) modulated signal transmis-

sion over power lines. Operating in the 10kHz to 490kHz

band, the programmable filters allow compliance with

CENELEC, FCC, and ARIB standards using the same

device.

Baseband

S Integrated Band Select Filter, AGC, and 10-Bit

ADC for Rx Path

S Integrated Wave-Shaping Filter, Programmable

Predriver Gain, and 10-Bit DAC for Tx Path

S Variable Sampling Rate Up to 1.2Msps

S Built-In 60dB Dynamic Range AGC and DC Offset

Cancellation

The MAX2991 transceiver provides two main paths:

transmit (Tx) path and receive (Rx) path. The transmit

path injects an OFDM modulated signal into the AC or

DC line. The transmit path is composed of a digital IIR

filter, digital-to-analog converter (DAC), followed by a

lowpass filter, and a preline driver. The receiver path is

for the signal enhancement, filtering, and digitization of

the received signal. The receiver is composed of a low-

pass and a highpass filter, a two-stage automatic gain

control (AGC), and an analog-to-digital converter (ADC).

The integrated AGC maximizes the dynamic range of the

signal up to 60dB, while the lowpass filter removes any

out-of-band noise, and selects the desired frequency

band. The ADC converts the enhanced and amplified

input signal to a digital format. An integrated offset can-

cellation loop minimizes the DC offset.

S Programmable Filters Operate in the CENELEC,

FCC, and ARIB Frequency Bands

S Single 3.3V Power Supply

S 70mA Typical Supply Current (Half-Duplex Mode)

S Extended Operating Temperature Range

Applications

Automatic Meter Reading

Home Automation

Heating Ventilation and Air Conditioning (HVAC)

Building Automation

Industrial Automation

Lighting Control

Sensor Control and Data Acquisition (SCADA)

Remote Monitoring and Control

Security Systems/Keyless Entry

Smart Grid

The MAX2991, along with the MAX2990 PLC baseband

modem, delivers the most cost-effective data communi-

cation solution over power-line networks in the market.

The MAX2991 is specified over the -40NC to +85NC

temperature range and is available in a 48-pin LQFP

package.
