General Description

General Description The HT2015 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 ponents provide all of the functions needed to satisfy HART physical layer requirements including modulation, demodulation, receive filtering, carrier detect and transmit-signal shaping.

The HT2015 is pin-patible with the SYM20C15.

Key Features

  • Can be used in designs presently using the SYM20C15 or equivalent type chip.
  • Single-chip, half-duplex 1200 bits per second FSK modem.
  • Bell 202 shift frequencies of 1200 Hz and 2200 Hz.
  • 3.3V-5.0V power supply.
  • Transmit-signal wave shaping.
  • Receive band-pass filter.
  • Low power: optimal for intrinsically safe.
