A5191HRTP Datasheet

Telecom Line Management ICs


The A5191HRTP is a single−chip, CMOS modem for use in highwayaddressable remote transducer (HART) field instruments and masters.The modem and a few external passive components provide all of thefunctions needed to satisfy HART physical layer requirementsincluding 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 circuitsare disabled during transmit operations and vice versa. This providesthe half−duplex operation used in HART communications. A5191HRTP 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 A5191HRTP Applications • HART Multiplexers• HART Modem Interfaces• 4 − 20 mA Loop Powered Transmitters
