InLink-CC™ HART Modem Module - Capacitor Coupled

InLink-CC is a HART protocol modem module that modulates logic level 1200 BAUD serial data onto a HART loop, and demodulates received HART data providing a 1200 BAUD serial bit stream. It allows designers to easily implement a HART compliant modem without knowledge of the HART physical layer requirements. InLink-CC interfaces to standard 3.3V logic and only requires 3 control lines; transmit, receive, and request-to-send (RTS). The InLink-CC small package size further simplifies integration into your design.
