Product description

The DE70322T is a complete AIS Class B (IEC 62287-1) technology demonstrator/reference design package that will enable manufacturers to quickly deploy an AIS Class B transceiver to the market.  This flexible platform provides a new low cost route to developing an AIS class B transceiver, taking it through certification and getting to market in a fast and trouble-free manner.

The DE70322T implements a dual-channel receiver / single transmitter on 161.975MHz (AIS channel 1) and 162.025MHz (AIS channel 2) with 25kHz channel spacing and 9600bps over-air data rate. The receivers are programmable across the entire marine band (156.000 to 162.050 MHz) while the transmitter is optimised for use in the upper marine band (160.000 to 162.050 MHz).

The design is a flexible platform based around the CMX7032 Marine AIS baseband and protocol processor.

Function Images

Two Function Images™ are available:

  • 7032/7042FI-1.x  providing full AIS Class B operation
  • 7032/7042FI-3.x  providing full marine AIS Class B operation with the addition of exactTrax™ operation

 

The on-board ARM microcontroller (STM32F411VET6) allows a USB-connected host to directly control the CMX7032 using CML script processing language, but also implements a basic Rx-only capability that can be used directly with a suitable PC-based plotter.

A JTAG header allows designers to implement their own code and/or implement a complete Class-B CSTDMA protocol stack.

There is sufficient memory and processing capability to implement  a Class-B SOTDMA (IEC 62287-2) protocol stack, however the RF output of the pcb is limited to 2W.
