Overview
The NCN5192MNRG, produced by onsemi, is a single-chip, CMOS modem designed for use in Highway Addressable Remote Transducer (HART) field instruments and masters. This modem integrates all the necessary functions to satisfy HART physical layer requirements, including modulation, demodulation, receive filtering, carrier detect, and transmit-signal shaping. It operates at a data rate of 1200 bits per second using phase continuous frequency shift keying (FSK) with frequencies of 1200 Hz and 2200 Hz. The device is optimized for low power consumption, making it suitable for intrinsically safe applications and is compatible with 3.3 V or 5 V microcontrollers.
