MAX2990 ABRIDGED DATA SHEET 19-4116 Rev 0 4/08 10kHz to 490kHz OFDM-Based Power Line Communication Modem General Description Features The MAX2990 power line communication (PLC) base- Combines the Physical Layer (PHY) and Media band modem delivers a cost-effective, reliable, half- Access Controller (MAC) duplex asynchronous data communication over AC Integrated Microcontroller with 32kB Password- power lines at speeds up to 100kbps. The MAX2990 is Protected Flash Memory and 8kB SRAM a highly integrated system-on-chip (SoC) that combines Maximum Effective Data Rate in Normal Mode the physical (PHY) and media access control (MAC) layers using Maxims 16-bit MAXQ microcontroller core. 32kbps at 10kHz to 95kHz and 100kbps at The MAX2990 utilizes OFDM modulation techniques to 10kHz to 490kHz enable robust data communication using the same Complies with electrical network that supplies power to all other CENELEC A (10kHz to 95kHz) devices on the network. CENELEC B (95kHz to 120kHz) The MAX2990 includes the MAXQ microcontroller core. CENELEC C (120kHz to 140kHz) The MAXQ is a 16-bit RISC microcontroller with 32kB flash FCC (10kHz to 490kHz) memory, 5.12kB of ROM, and 8kB SRAM, of which 4kB ARIB (10kHz to 450kHz) that can be simultaneously accessed by the MCU and the Includes Forward Error Correction (FEC) PHY. The MAX2990 is integrated with modules for serial 2 Mechanism and CRC16 communication (SPI, I C, UART) and a real-time clock (RTC) for time stamping, in addition to standard blocks Includes Fast DES Engine as the such as timers, GPIO, and external interrupts. Encryption/Decryption Coprocessor and CRC32 The MAX2990 transceiver is based on an orthogonal Jammer Cancellation for FCC and ARIB frequency division multiplexing (OFDM) technique that User-Configured Start and End Operating allows robust data transmission over poor channel con- Frequency ditions specifically for environments with impulsive Carrier Sense Multiple Access/Collision noise. OFDM with binary phase shift key (BPSK) and Avoidance (CSMA/CA) Channel Access forward error correcting (FEC) blocks are used because of their inherent adaptability in the presence of Arbitration frequency selective channels without the use of equal- Automatic Repeat Request (ARQ) to Enhance izers, resilience to jammer signals, robust communica- Error Detection and Improve Data Reliability tions in the presence of group delay spread, and 2 Supports SPI, I C, and UART Interfaces robustness to impulsive noise. The MAX2990 features Real-Time Clock (RTC) jammer cancellation that removes constant sinusoidal interference signals for FCC and ARIB bands. Privacy PWM Counters is provided by DES encryption. Built-In Test Mode Engine for Identifying Channel The MAX2990 is available in a 64-pin LQFP package Conditions and is specified over the -40C to +85C extended tem- perature range.
