MAX2992:G3-PLC MAC/PHY Powerline Transceiver

Industry's First G3-PLC Compliant Modem Provides Reliable Communication at Speeds Up to 300kbps

The MAX2992 powerline communication (PLC) baseband modem delivers half-duplex, asynchronous data communication over AC power lines at speeds up to 300kbps (full FCC band data rate). The MAX2992 is a system-on-chip (SoC) that combines the physical (PHY) and media access control (MAC) layers using Maxim's 32-bit MAXQ30 microcontroller core. The MAX2991 integrated analog front-end transceiver interfaces seamlessly with the MAX2992, and together with the MAX2992 G3-PLC™ firmware, forms a complete G3-PLC-compliant modem solution. The MAX2992 utilizes OFDM techniques with DBPSK, DQPSK, D8PSK modulation and forward error correction (FEC) to enable robust data communication using the electrical power grid. The design provides inherent adaptability to frequency selective channels, robustness in the presence of group delay, and immunity to impulsive noise. To allow for regulatory compliance, the MAX2992 incorporates a programmable tone notching mechanism. This allows the notching of certain frequency bands in the transmit spectrum of the modem. This feature also provides an alternative method to address coexistence with other narrowband transmitters such as legacy FSK-based PLC systems. The MAX2992 MAC incorporates a 6LoWPAN adaptation layer to support IPv6 packets. An enhanced CSMA/CA and ARQ, together with the mesh routing protocol, supports all common MAC layer services for various network topologies. Intelligent communication mechanisms adapt and enhance system performance over a range of channel conditions. These mechanisms include channel estimation, adaptive tone mapping, and routing protocols. An on-chip CCM (an extension of CCM specified in IEEE® 802.15.4) authentication coprocessor with AES-128 encryption/decryption provides security and authentication.
