CMX885 : The CMX885 is a half-duplex, audio, signalling and data processing IC for use in Marine VHF radio systems. Comprehensive audio processing facilities include complete audio processing, filtering, pre- or deemphasis and frequency inversion scrambling. Signal routing and filtering is included to assist host µC based signal encoding/decoding applications. 1200bps Digital Selcall (DSC) or Automatic Transmitter Identification System (ATIS) modem with protocol support and NWR decoding are supported. A DTMF encoder/decoder, a full complement of auxiliary ADCs and DACs and dual synthesised clock outputs are included in this low power PMR processor. The device also has flexible powersaving modes and i.
