MAX2992 G3-PLC MAC/PHY Powerline Transceiver Benefits and Features General Description G3-PLC Compliant The MAX2992 powerline communication (PLC) baseband modem delivers half-duplex, asynchronous data commu- Prestandard Conformance: IEEE P1901.2, ITU nication over AC power lines at speeds up to 300kbps (full G.9903 FCC band data rate). The MAX2992 is a system-on-chip Frequency-Band Compliant with CENELEC, FCC, (SoC) that combines the physical (PHY) and media access and ARIB control (MAC) layers using Maxims 32-bit MAXQ30 micro- Operating Frequency from 10kHz to 490kHz controller core. The MAX2991 integrated analog front-end transceiver interfaces seamlessly with the MAX2992, and Single-Chip Solution Integrating Physical Layer together with the MAX2992 G3-PLC firmware, forms a (PHY) and Media Access Controller (MAC) complete G3-PLC-compliant modem solution. Two UART and Two SPI Interfaces The MAX2992 utilizes OFDM techniques with DBPSK, Supports IPV6-Compatible Networking Layer DQPSK, D8PSK modulation and forward error correc- 6LoWPAN IPV6 Header Compression Maximizes tion (FEC) to enable robust data communication using Payload Size the electrical power grid. The design provides inherent Dynamic Routing Mechanism Supports Mesh adaptability to frequency selective channels, robustness Networking in the presence of group delay, and immunity to impulsive CSMA/CA (Carrier Sense Multiple Access with noise. To allow for regulatory compliance, the MAX2992 Collision Avoidance/Channe l Access) incorporates a programmable tone notching mechanism. High-Speed, Reliable Communication This allows the notching of certain frequency bands in the Data Rate of up to 300kbps transmit spectrum of the modem. This feature also pro- Two Layers of Forward Error Correction (FEC) and vides an alternative method to address coexistence with Cyclic Redundancy Check (CRC16) other narrowban d transmitters such as legacy FSK-based Enhanced FEC with Reed-Solomon and Viterbi PLC systems.
