DESCRIPTION
The programmable DSP cores support advanced audio features, including multi-mic wideband noise reduction and beamforming, highperformance acoustic echo cancellation (AEC), stereo ambient noise cancellation (ANC), speech enhancement, advanced media enhancement, and many more. The DSP cores are supported by a fully-flexible, all-digital mixing and routing engine with sample rate converters, for wide usecase flexibility. A SLIMbus interface supports multi-channel audio paths and host control register access. Multiple sample rates are supported concurrently via the SLIMbus interface. Three further digital audio interfaces are provided, each supporting a wide range of standard audio sample rates and serial interface formats. Automatic sample rate detection enables seamless wideband/narrowband voice call handover. Three stereo headphone drivers each provide stereo ground-referenced or mono BTL outputs. 110dB SNR, and noise levels as low as 2μVRMS, offer hi-fi quality line or headphone output.
