    DATA SHEET www.onsemi.com HART Modem A5191HRT Description The 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 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. Features  Single−chip, Half−duplex 1200 Bits per Second FSK Modem  Bell 202 Shift Frequencies of 1200 Hz and 2200 Hz  3.0 V − 5.
