CML CMX7042
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/CMX7042, unless otherwise stated. The AIS system allows ships and base stations to communicate their position and other data to each other without the need for a centralised controller.FEATURES
