MAX2981

19-4736; Rev 0; 7/09 www.DataSheet4U.com Integrated Powerline Communication Analog Front-End Transceiver and Line Driver General Description The MAX2981 powerline communication analog frontend (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 previously required system components and complies with 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. 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. 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 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 Tem...
