FirmASIC technology-based marine AIS chips make waves

24 January 2007 Telecoms, Datacoms, Wireless, IoT

CML says its new CMX7032 and CMX7042 are making waves in the global marine AIS (automatic identification system) transponder market. These highly integrated baseband signalling processors fulfil the requirements of all marine AIS transponders, AIS Rx-only units and Aton (Aids to Navigation) systems, on both large and small vessels.

The CMX7032 and CMX7042 devices have been specifically designed for use in AIS units utilising Limiter-Discriminator RF architecture. Both are half-duplex in operation, comprising two parallel Limiter-Discriminator Rx paths and one I and Q or two-point modulation Tx path, configurable for either marine AIS or DSC operation.

Both devices push on-chip integration to new levels by performing signal modulation/demodulation with associated AIS functions, such as training sequence detection, NRZI conversion and HDLC processing (flags, bit stuffing, CRC generation and checking). Combined with the integrated Tx/Rx data buffers, the overall host microcontroller processing requirements are reduced. Auxiliary DAC and ADC functions are provided to further simplify system design.

The two parts have identical core functions. The CMX7032 provides maximum integration with the inclusion of two on-board auxiliary RF synthesisers. The CMX7042 comes without RF synthesisers, offering maximum RF system flexibility and the smallest foot-print package. Both use CML's FirmASIC component technology. On-chip sub-systems are configured by a Function Image; this is a data file that is uploaded during device initialisation and configures the device's function and feature-set. The Function Image can be loaded automatically from an optional external EEPROM or from a host microcontroller over the built-in C-BUS serial interface, The device's features and functions can be enhanced by subsequent Function Image releases, facilitating in-field upgrades.

The CMX7032 and CMX7042 operate from a single 3,3 V supply.
