NCN5192
HART Modem
Description
The NCN5192 is a singlechip, 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 transmitsignal shaping. In addition, the NCN5192 also has an
integrated DAC for low-BOM current loop slave transmitter
implementation.
The NCN5192 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
halfduplex operation used in HART communications.
