The CMX885 is a half-duplex, audio, signalling and data processing IC for use in Marine VHF radio systems.
Complete voice-band processing, filtering, pre- or de-emphasis and frequency inversion scrambling. Signal routing and filtering is included to assist host µC based signal encoding/decoding applications.
A 1200bps Digital Selcall (DSC)/Automatic Transmitter Identification System (ATIS) modem with protocol support and National Oceanic and Atmospheric Administration (NOAA) National Weather Radio (NWR) decoding are supported.
A DTMF encoder/decoder, a full complement of auxiliary ADCs and DACs and dual synthesised clock outputs are included.
The device also has flexible powersaving modes and is available in 48-pin VQFN and LQFP packages.
