The MAX2990 is a 10kHz to 490kHz OFDM-based power line communication modem. It provides a cost-effective, reliable, half-duplex asynchronous data communication over AC power lines at speeds up to 100kbps.
The MAX2990 is a highly integrated system-on-chip (SoC) designed for cost-effective, reliable half-duplex asynchronous data communication over AC power lines. It operates in the frequency range of 10kHz to 490kHz using Orthogonal Frequency Division Multiplexing (OFDM) techniques to ensure robust transmission even in environments with impulsive noise.
The device combines the Physical Layer (PHY) and Media Access Control (MAC) layers, featuring a built-in 16-bit MAXQ microcontroller core. It includes 32kB of password-protected flash memory, 8kB of SRAM, and supports various communication interfaces such as SPI, I2C, and UART. The modem also incorporates features like DES encryption for privacy, jammer cancellation for FCC and ARIB bands, and a real-time clock (RTC).
