CML Microcircuits has introduced a half-duplex audio, signalling and data processing IC for use in Marine VHF radio systems.

The new CMX885 Marine VHF baseband processor is designed to meet the global requirements of low-cost, highly-integrated marine VHF transceivers by offering complete audio processing with selectable audio processing order.

The CMX885 is a global marine audio and signalling solution with in-band signalling capabilities including DSC, ATIS, DTMF, NWR WAT and SAME. Its embedded functionality also allows a very small, low-power, low-cost host microcontroller to be utilised as part of the overall marine VHF transceiver system. Features include digital gain control, pre/de-emphasis, filtering, soft limiting and voice scrambling options.

Suitable for both portable and fixed (maritime) mobile transceivers, the device utilises dual Rx channel operation for DSC class D conformance. It also boasts a 1200 bps Digital Selcall (DSC) modem with protocol support and an Automatic Transmitter Identification System (ATIS) modem, as well as NOAA weather radio decoding support.

A full complement of auxiliary ADCs, DACs and dual synthesised clocks is included in this low-power marine VHF processor. A minimum of external components is required for the device that also offers flexible power saving modes. The CMX885 operates between 3,0 and 3,6 V and is available in 48-pin VQFN and LQFP packages.
