NCN5192NG Evaluation
Board User's Manual
Introduction
The NCN5192NGEVB includes all external components
needed for operating NCN5192 and demonstrates the small
PCB surface area such an implementation requires. The
EVB allows easy design of HART implementations using
NCN5192.
Overview
The NCN5192 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 NCN5192 also includes an internal 16-bit
sigma-delta modulation DAC for easy implementation of
slave devices. An SPI bus provides easy communication to
this DAC and internal registers.
