Marine AIS Data Processor Designed For Limiter-Discriminator Based RF Systems

The CMX7032 CMX7042 is half duplex in operation, comprising two parallel Limiter-Discriminator Rx paths and one I & Q or two-point modulation Tx path. The Rx paths are configurable for AIS or DSC operation, the Tx for AIS only. The device performs signal modulation/demodulation with associated AIS functions, such as training sequence detection, NRZI conversion and HDLC processing (flags, bit stuffing/de-stuffing, CRC generate/check). Integrated Rx/Tx data Buffers are also provided. This greatly reduces the processing requirements of the host C. Provision of a number of auxiliary ADCs and DACs further simplifies the system hardware design, reducing the overall equipment cost and size. The CMX7042 is identical in functionality to the CMX7032 with the exception that the two on-chip RF Synthesisers have been deleted, which enables it to be supplied in a smaller package. This document refers to both parts generically as the CMX7032 unless otherwise stated. By Consumer Microcircuits Limited
