CS47L35

Smart Codec with Low-Power Audio DSP

• Three full digital-audio interfaces

Features

— Standard sample rates from 8 to 192 kHz

• 450 MIPS, 450 MMAC multicore audio-signal processor

• Programmable wideband, multimic audio processing

— Transmit-path noise reduction and echo cancelation

— Wind-noise, side-tone, and other programmable filters

• Integrated multichannel 24-bit hi-fi audio hub codec

— 101-dB signal-to-noise ratio (SNR) mic input (48 kHz)

— 122-dB SNR headphone playback (48 kHz)

— Multichannel time-division multiplexing (TDM) support

on AIF1

• Flexible clocking, derived from MCLKn, AIFn, or SLIMbus

• Low-power frequency-locked loop (FLL) supports

reference clocks down to 32 kHz

• Configurable functions on up to 16 general-purpose

input/output (GPIO) pins

• Sensor-hub connectivity, with event time-stamp functions

• Integrated regulators and charge pumps

• Up to six analog or four digital microphone (DMIC) inputs

• Stereo headphone/earpiece/line output driver: 30 mW

into 32- load at 0.1% total harmonic distortion + noise

(THD+N)

• Small WLCSP package, 0.4-mm ball array

Applications

• Class D speaker and digital (pulse-density modulation,

PDM) output interfaces

• Smartphones and multimedia handsets

• Tablets and mobile Internet devices

• SLIMbus audio and control interface
