Product Introduction

Overview

The A5191HRTLG-XTP, 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 detection, and transmit-signal shaping. It operates using phase-continuous frequency shift keying (FSK) at a data rate of 1200 bits per second.
