CS47L15 - Smart Codec

Description

The CS47L15 is a highly integrated, low-power audio hub for smartphones, tablets, and other portable audio devices including wearable technology.

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

Features

  • Earpiece, speaker, and digital (pulse-density modulation, PDM) output interfaces.
  • 150 MIPS, 150 MMAC audio-signal processor.
  • Two-way stereo PDM interface.
  • Low-power, always-on voice trigger capability.
  • Three full digital-audio interfaces.
  • Speaker protection algorithm support.
  • Standard sample rates from 8 to 192 kHz.
  • Event loggers with time-stamp and interrupt functions.
  • Multichannel support on AIF1 and AIF2.
