CMX7158 - Duplex Audio Scrambler

Description

The CMX7158 is a full-duplex, frequency inversion audio scrambler IC.

This makes it a suitable device for use in multifunction audio systems as well as mobile and hand portable Cellular / Bluetooth / PMR / LMR radio systems.

Features

  • Fully independent Tx and Rx paths.
  • Programmable Inversion points.
  • MIC path AGC.
  • VOX detection.
  • DTMF encoder / decoder.
  • Selcall encoder / decoder.
  • Digital Gain Adjustment.
  • C-BUS Serial Interface to Host µController.
  • Bypass mode for HD Audio (up to 7kHz).
  • Clear Mode.
  • TxENA and RxENA outputs.
  • Flexible Powersave Modes.
  • Low-power 3.0 to 3.6V Operation.
  • Small 48-pin Q3 VQFN Package.
