Brief Description
The DE70321 is a complete AIS Class B (IEC 62287) technology demonstrator aimed at speeding
manufacturers' design and development of AIS Class B 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:
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.

... PC interface when using FI-1.x. The DE70321 can also be used in Rx-only mode with FI-2.x. In this mode, typical operation is to use the EEPROM on the DE70322 which will automatically load the FI at power-on. NMEA-083HS data is then automatically output on the RS-232 port as soon as valid data has been detected ...
