Description
Designed for AIS Class B Implementation, the CMX7032 is a highly integrated, half-duplex, AIS baseband signalling processor IC with two on-chip RF synthesisers.
Comprising two parallel limiter-discriminator Rx paths and one I and Q or two-point modulation Tx output path, the CMX7032 fulfills the requirements of the Class B marine AIS system. Each of these paths is configurable for AIS or DSC operation.

The CMX7032 performs signal modulation/demodulation of associated AIS functions, such as training sequence detection, NRZI conversion and HDLC processing (flags, bit-stuffing/de-stuffing, CRC generation/checking). Raw AIS data and AIS burst data handling options are selectable.

Use of the CMX7032 is made more attractive by the provision of two RF synthesisers and two synthesised system clock generators on-chip. To further simplify the system design process, Integrated Rx/Tx buffers with gain control and auxiliary ADCs and DACs are also provided.

Evaluation Kits:

    PE0201, PE0002 and DE70321 are available for the evaluation of this product.
