The CS47L85 combines a 900 MIPS 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 cancelation (AEC), stereo ambient noise cancelation (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 3 stereo, 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 1.8 V and 1.2 V external supplies.
Features
900 MIPS, 900 MMAC multi-core audio-signal processor
Enhanced DRE processing (eDRE) for 121dB SNR
Fixed function signal-processing functions
Multi-channel asynchronous sample-rate conversion
Integrated multi-channel 24-bit hi-fi audio hub codec
Four digital microphone inputs (two stereo interfaces)
Three stereo headphone/earpiece/l
ine output drivers
Two 2 W Class D speaker output drivers
Four full digital audio interfaces
Sample rates 8 kHz up to 192 kHz
Flexible clocking, derived from MCLKn or AIFn
Three low power frequency-locked loops (FLLs) support reference clocks down to 32 kHz
Ultra low power consumption for “always on” functions
Configurable functions up to 40 GPIO pins
Integrated regulators and charge pumps
Small WCSP package, 0.4-mm, 176-ball array
