Maxim launched Maxim Integrated Products highly integrated electric, Inc ( NASDAQ: MXIM ) introduced the first to work in harsh industrial environment of broadband, HomePlug R 1 compatible power line communication transceiver MAX2982. MAX2982 has the characteristics of high integration, to provide great flexibility in design. The receiver in a reliable model with the - 1dB signal-to-noise ratio ( SNR ), to ensure that the noisy environment and reliable communication. Device working at - 40 degrees C to + 105 degrees C temperature range, has passed the AEC-Q100-Rev-G certification standards, capable of harsh application environment. MAX2982 is a simple design of industrial grade, broadband power line communication solutions, is suitable for the automatic control, remote monitoring, energy management, wireless base station monitoring and a local area network ( LAN ).

　　Industrial application needs reliable cable communication

　　The industry standard HomePlug 1 power line communication chip set in residential applications increasingly widespread. Nevertheless, because of the existing products do not have industrial and commercial applications of reliability required and temperature rating, many applications can not make full use of advantages of the technique. In addition, the commercial and industrial power line communication environment with strong noise interference, unlike most HomePlug modem used in residential environment. Therefore, industrial application needs for power line receiver and narrowband interference circuit optimization, in order to ensure that its work in the environment of high performance. Finally, the automation industry hope laying single cable power supply and communication network, the network needs to have a longer service life and in the harsh environment of high precision performance, reliable monitoring, remote control sensor, motor and other systems. The application of the need for validated, reliable power line network to support. The introduction of the MAX2982 for this type of application provides the ideal solution.

　　Via broadband power line communication scheme of single cable power supply and control

　　MAX2982 for high performance, real time control and automation application optimization. The device has 333 s low latency response time and 14Mbps data rate, in large-scale automation equipment in the network to support broadband data transmission. MAX2982 has a 512 address bridging table and point to multipoint addressing function, recording, monitoring, control network of hundreds of HomePlug modem. This technique eliminates the traditional scheme for long distance, special communication cable. Optional firmware to provide greater anti-interference ability, further expand the range of communication. With key management of 56 DES / three DES ( 3DES ) encryption to ensure security communication.

　　" We’ve partnered with Maxim to provide high reliability industrial automation products for the power line communication solution. Maxim gives us power line technology and extended temperature range integrated technology ", SEW Eurodrive senior research expert Rochus Hien said. " MAX2982 provide low delay, high speed, reliable power line communication is that we can provide industry-leading product cornerstone," Hien added. Maxim signal processing and conversion products line managing director James Bates said in a statement: " we are very pleased to be able to work with SEW Eurodrive, see Maxim r power line products for industrial application value."

　　Open architecture for accelerating system optimization

　　MAX2982 is fully compatible with HomePlug 1, the programmable device application interface allows the use of after market optimized firmware. The interface includes: a 10 / 100 Ethernet, UART, USB, JTAG, MII, RMII and high speed FIFO. The boot code option allows the use of applications related to MAX / PHY configurations, each configuration may be in response to various parameters are optimized. Use of scalable MAC, can realize the application of related spectrum shaping, including bandwidth and notch adjustment function. 24 general input / output ( GPIO ) pin for network data handshake and signaling.

　　The MAX2982 transceiver with power line analog front end ( AFE ) and line driver MAX2981 use, constitute a complete broadband power line chip set. MAX2982 uses a 128 pin, LQFP leadless package.
