MAX2982 Industrial Broadband Powerline Modem General Description Features S Single-Chip Powerline Networking Transceiver The MAX2982 powerline transceiver utilizes state-of-the-art CMOS design techniques to deliver the highest level of S HomePlug 1.0 Compliant performance, flexibility, and operational temperature range S -40C to +105C Operating Temperature Range at reduced cost. This highly integrated design combines S Integrated Temperature Sensor the media access control (MAC) and the physical (PHY) S Up to 14Mbps Data Rate layers in a single device. The MAX2982 digital baseband and its companion device, the MAX2981 analog front-end S Low-Rate Adaptation (LORA) Operation Option (AFE) with integrated line driver, offer a complete high- Provides -2dB SNR Performance at 500kbps speed powerline communication solution fully compliant S 4.49MHz to 20.7MHz Frequency Band M with HomePlug 1.0 Powerline Alliance Specification. S Flexible MAC/PHY The MAX2982 offers reliable broadband communication Field Upgradable Firmware Using TFTP for industrial environments. The PHY layer comprises an Spectral Shaping Including Bandwidth and 84-carrier OFDM modulation engine and forward error Notching Capability correcting (FEC) blocks. The OFDM engine can modulate Programmable Preamble the signals in one of four modes of operation: DBPSK, 128kB Internal SRAM DQPSK (1/2 rate FEC), DQPSK (3/4 rate FEC), and ROBO. S Advanced Narrowband Interference Rejection The MAX2982 offers -1dB SNR performance in ROBO Circuitry mode, a robust mode of operation, to maintain commu- S 84-Carrier, OFDM-Based PHY nication over harsh industrial line conditions. Additionally, Automatic Channel Adaptation advanced narrow-band interference rejection circuitry FEC (Forward Error Correction) provides immunity from jammer signals. DQPSK, DBPSK Modulation The MAX2982 offers extensive flexibility by integrating an Enhanced ROBO Mode with -1dB SNR ARM946E-S microprocessor allowing feature enhance- S Large Bridge Table: Up to 512 Addresses ment, worldwide regulatory compliance, and improved S 56-Bit DES Encryption with Key Management for testability.
