HART Communication Controller
HART Communication Controller 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 HT1200M is pin-compatible with the SYM20C15. See the Pin Description and Functional Description sections for details on pin compatibility with the SYM20C15. The HT1200M 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.

The role of temperature in transmitters
The role of temperature in the transmitter For the temperature range of the temperature transmitter, usually a transmitter will calibrate two temperature ranges, that is, the normal operating temperature range and the temperature compensable range. The normal operating temperature range refers to the temperature range when the transmitter is not damaged under working conditions. When the temperature compensation range is exceeded, the performance index of its application may not be achieved. The temperature compensation range is a smaller range than the operating temperature range. typical range. Working within this range, the transmitter will definitely achieve its due performance.
