The CS47L24 combines an advanced 300 MIPS dual core DSP with a high performance audio hub codec embedded with SoundClear® software technology to add voice to mobile, wearable and smart home devices. SoundClear Control enables always on voice with the option of local command and control - all at power levels that are kind on battery life. This highly integrated IC features a variety of power efficient, fixed function, audio-processing blocks supported by a fully flexible, all digital mixing and routing engine with sample rate converters to provide design flexibility across a variety of platforms. The power, clocking and output driver architectures of the CS47L24 are designed to maximize battery life for voice, music and standby modes using 1.8 and 1.2V external supplies.
