Description
The DE70321 is a complete AIS Class B (IEC 62287) technology demonstrator aimed at speeding manufacturers' design and development of AIS Class B transponders and AIS receiver products using the CMX7032 AIS Class B Baseband Processor with RF Synthesiser IC.
The design is a flexible platform to allow users to configure and evaluate with two build options:
  • Class B Transceiver (using CMX7032 FI-1.x)
  • Dual Channel Rx-only (using CMX7032 FI-2.x)
The default board configuration is for dual channel receive on 161.975MHz (AIS channel 1) and 162.025MHz (AIS channel 2) with 25kHz channel spacing and 9600bps over-air data rate. An EEPROM is included which can automatically load the Function Image™ FI-2.x into the CMX7032 at power-up.
Received data is automatically provided as NMEA 0183-HS sentences at 38,400bps from the DB9 RS232 port.

Function Image™ FI-1.x allows full host control over all CMX7032 functions whereas Function Image™ FI-2.x automatically programs the CMX7032 RF synthesisers to the correct frequencies.
All necessary RF circuits, such as VCOs, a 2 watt PA, harmonic filter, antenna switching and LNA, are provided on the DE70321 to facilitate easy evaluation and demonstration of the design as a Class B unit.

A C-BUS interface is provided for control of the CMX7032 by a host microcontroller (required to perform the higher level protocol functions on a Class B implementation). The design is production engineered for low cost, with minimum number of component types and values and uses only low-cost off-the-shelf components.


Further Design Support
There is available, on the CML technical portal, a library of files (Schematics, Bill of Materials and Gerber files) that will further assist in the progress of the design-in process.
