Single-chip, half-duplex 1200 bits per second FSK modem  
Bell 202 shift frequencies of 1200Hz and 2200Hz  
3.3V - 5.0V power supply  
Transmit-signal wave shaping  
Receive band-pass filter  
Low power: optimal for intrinsically safe applications  
CMOS compatible  
Internal oscillator requires 460.8kHz crystal or ceramic resonator  
Meets HART physical layer requirements  
Industrial temperature range of -40°C to +85°C  
Available in 28-pin PLCC and 32-pin LQFP packages  
2.0 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 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.
