CS47L90 - Hi-Fi Audio Smart Codec

Description

The CS47L90 is a highly integrated, low-power audio and sensor hub system for smartphones, tablets, and other portable audio devices.

It combines an advanced DSP feature set with a flexible, high-performance audio hub codec.

Features

  • Low-power, always-on voice trigger capability.
  • 975 MIPS, seven DSP-core audio signal processor.
  • Inter-DSP memory sharing.
  • Multichannel asynchronous sample-rate conversion.
  • Multiline SLIMbus® audio and control interface.
  • Event loggers with time-stamp and interrupt functions.
  • Four full digital-audio interfaces.
  • Programmable wideband, multimic audio processing.
  • Cirrus Logic® mono ambient noise cancelation.
