The CS47L35 combines an advanced DSP feature set with a highly integrated audio codec to deliver the Cirrus Logic voice and audio experience for mid-tier smartphones. The CS47L35 features a 450 MIPS three-core audio signal processor with a high performance 4/3 channel, 24-bit high-fidelity codec embedded with SoundClear® software technology to support multiple concurrent audio functions including multi-microphone wideband noise reduction, speaker protection, acoustic echo cancelation (AEC), low power single and multi-trigger word detection and engine support, and advanced speech and media enhancement.
Features
450 MIPS, 450 MMAC multi-core audio-signal processor
Sensor hub connectivity, with event time-stamp functions
Programmable wideband, multi-mic audio processing
Four ADCs, 100 dB SNR microphone input, three DACs, 122 dB SNR headphone playback
Integrated multichannel 24-bit hi-fi audio hub codec
Up to six analog or four digital microphone inputs
Stereo headphone/earpiece/l
ine output driver
Earpiece, speaker and digital (PDM) output interfaces
Three full digital audio interfaces
Flexible clocking, derived from MCLKn, AIFn or SLIMbus
Low power frequency-locked loops (FLLs) support reference clocks down to 32 kHz
Configurable functions on up to 16 GPIO pins
Integrated regulators and charge pumps
Small WCSP package, 0.4-mm ball array
