CML Microcircuits (USA) Inc. RF Misc ICs and Modules CMX885Q3

The CMX885Q3 is a half-duplex audio, signalling, and data processing integrated circuit designed for Marine VHF radio systems. It features comprehensive audio processing capabilities, including selectable audio processing order, pre- and de-emphasis, and frequency inversion scrambling. The device supports a 1200bps Digital Selcall (DSC) modem and Automatic Transmitter Identification System (ATIS) protocol, along with NOAA decoding. This processor includes a DTMF encoder/decoder, dual auxiliary ADCs, four auxiliary DACs, and dual synthesized clock outputs. It operates with a low power supply range of 3.0V to 3.6V and offers flexible power-saving modes. The CMX885Q3 is available in compact 48-pin VQFN and LQFP packages, making it suitable for space-constrained applications. Its C-BUS serial interface allows for easy integration with host microcontrollers, enhancing its versatility in various marine communication applications.
