The A5191HRTPG-XTP is a single-chip, CMOS modem in 28 pin PLCC package. This modem is used 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. It uses phase continuous frequency shift keying (FSK) at 1200bits 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. It is used in HART multiplexers, HART modem interfaces and 4mA to 20mA loop powered transmitters.
- Power supply of 3V to 5.5V
- Bell 202 shift frequencies of 1200Hz and 2200Hz
- Transmit signal wave shaping
- Receive band pass filter
- Low power, optimal for intrinsically safe applications
- Compatible with 3.3V or 5V microcontroller
- Internal oscillator requires 460.8KHz crystal or ceramic resonator
- Meets HART physical layer requirements
- Industrial temperature range from -40°C to +85°C
