Introduction

AI Translation

The A5191HRT is a single-chip CMOS modem for Highway Addressable Remote Transmitter (HART) field instruments and master devices. This modem, along with a small number of external passive components, provides all the functions required to meet the HART physical layer specifications, including modulation, demodulation, receive filtering, carrier detection, and transmit signal shaping. The A5191HRT uses continuous-phase Frequency Shift Keying (FSK) at 1200 bits per second. To conserve power, the receive circuitry is disabled during transmit operations, and vice versa. This provides the half-duplex operation used in HART communications.
