A5191HRT
HART Modem
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 − 5.5 V Power Supply
• Transmit−signal Wave Shaping
• Receive Band−pass Filter
• Low Power: Optimal for Intrinsically Safe Applications
• Compatible with 3.3 V or 5 V Microcontroller
• Internal Oscillator Requires 460.8 kHz Crystal or Ceramic Resonator
• Meets HART Physical Layer Requirements
• Industrial Temperature Range of −40°C to +85°C
• Available in 28−pin PLCC, 32−pin QFN and 32−pin LQFP Packages
• These are Pb−Free Devices
Applications
• HART Multiplexers
• HART Modem Interfaces
• 4 − 20 mA Loop Powered Transmitters
