A5191HRT: Industrial HART-protocol modem

Datasheet: HART Modem

Product Overview

» Product Change Notification
A5191HRT is a single-chip, CMOS modem for use in highway addressable remote transducer (HART) field instruments and masters. The modem and a few external passive components provide all of the functions needed to satisfy HART physical layer requirements including modulation, demodulation, receive filtering, carrier detect, and transmit-signal shaping. The A5191HRT is pin-compatible with the SYM20C15. See the Pin Description and Functional Description sections for details on pin compatibility with the SYM20C15. The A5191HRT uses phase continuous frequency shift keying (FSK) at 1200 bits per second. To conserve power, the receive circuits are disabled during transmit operations and vice versa. This provides the half-duplex operation used in HART communications.
