Overview

NCN5193 HART Modem Description The NCN5193 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.
In addition, the NCN5193 also has an integrated DAC for low-BOM current loop slave transmitter implementation.
The NCN5193 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 • 1.
8 V − 3.
5 V Power Supply • Transmit−signal Wave Shaping • Receive Band−pass Filter • Low Power: Opt...
