Product description

The SCT7033 is a complete, proven, protocol solution that seamlessly integrates with CML’s CMX7032 Marine AIS Baseband Processor and allows designers and manufacturers to quickly develop AIS Class B CSTDMA transceivers, targeting emerging market applications.

AIS (Automatic Identification System) is governed by well-established marine standards intended, primarily, to allow ships to view marine traffic in their area and to be seen by that traffic.  The standards define technical and operating parameters to ensure correct interworking between equipment and as such define the communications protocols that are to be used.

The SCT7033 integrates a proven protocol stack meeting these requirements.  It supports CSTDMA data transmission as well as providing flexible interfacing to GNSS receivers, NMEA0183 marine communications bus, status LEDs and USB/UART interfaces.  The device automatically configures the CMX7032, CML’s AIS modem processor and PLLs to the appropriate AIS and marine radio channels.
