NCN49597 Power Line Communication Modem The NCN49597 is a powerful spread frequency shift keying (SFSK) communication systemonchip (SoC) designed for communication in hostile environments. www.onsemi.com It combines a low power ARM Cortex M0 processor with a high precision analogue front end. Based on 4800 baud SFSK dualchannel technology, it offers an ideal compromise between speed and robustness. Pincompatible with its predecessor, the AMIS49587, this new generation chip extends the communication frequency range to cover all CENELEC bands for use in applications such as emetering, home 152 automation and street lighting. The NCN49597 benefits for more than QFN52 8x8, 0.5P 10 years of field experience in emetering and delivers innovative CASE 485M features such as a smart synchronization and inband statistics. Fully reprogrammable, the modem firmware can be updated in the field. Multiple royaltyfree firmware options are available from MARKING DIAGRAM ON Semiconductor refer to the separate datasheets for details. The 52 configurable GPIOs allow connecting peripherals such as LCDs or 1 metering ICs.
