A5191HRT
HART Modem
Description
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.
(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.
