Integrated Powerline Communication Analog  
Front-End Transceiver and Line Driver  
MAX2981  
General Description  
Features  
The MAX2981 powerline communication analog front-  
end (AFE) and line-driver IC is a state-of-the-art CMOS  
device that delivers high performance at low cost. This  
highly integrated design combines an analog-to-digital  
converter (ADC), digital-to-analog converter (DAC),  
adaptive gain control (AGC), filters, and line driver on a  
single chip. The MAX2981 substantially reduces previ-  
ously required system components and complies with  
o HomePlug 1.0 Compliant  
o Fully Integrated AFE and Line Driver  
o Fully Compatible with the MAX2982/MAX2986  
o Pin-to-Pin Compatible with the MAX2980  
o Seamless Interface to Third-Party PHY ICs  
o Fully Integrated, 10-Bit, 50Msps ADC and DAC  
o 56dB Adaptive Gain Control  
®
the HomePlug 1.0 standard.  
Combined with Maxim’s integrated PHY/MAC digital  
baseband, the device delivers the most flexible and  
cost-effective solution. The advanced design of the  
MAX2981 allows operation without external control,  
enabling simplified connection to a variety of HomePlug  
1.0 digital PHY ICs.  
o Line Impedance Drive Capability as Low as 10Ω  
o Line-Driver Bypass Mode  
o 220mA in Rx Mode and 150mA in Tx Mode at 3.3V  
o -40°C to +105°C Operating Temperature Range  
o AEC-Q100 Rev F (Automotive) Qualified  
o 64-Pin LQFP Package  
The MAX2981 is specified over the -40°C to +105°C  
automotive temperature range and is offered in a 64-pin  
lead-free LQFP package. The device is qualified to the  
AEC-Q100 Rev F automotive standard.
