The CS47L85 combines a 900MIPS multi-core audio signal processor with a high performance 6/8 channel 24-bit high-fidelity codec embedded with soundclear® software technology to support multiple concurrent audio functions including multi-microphone wideband noise reduction, acoustic echo cancellation (AEC), mono active noise cancellation (ANC) and speed and media enhancement. Soundclear control provides “always on, always listening” multi-trigger word detection without keeping the applications processor awake to conserve standby-mode power. Soundclear sense supports applications that increase contextual awareness, including advanced motion sensing and pedestrian navigation functionality. The IC also includes 3stereo, multi-purpose headphone output drivers plus 2 stereo class D speaker output drivers, and a 4-channel digital speaker interface. The power, clocking and output driver architectures of the CS47L85 are designed to maximize battery life for voice, music and standby modes using 1.8V and 1.2V external supplies.
