• 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.
