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