WM5110 Datasheet | Wolfson Microelectronics

w Low Power Audio System with Wolfson my Zone™ Ambient Noise Cancellation and Echo Cancellation DESCRIPTION The WM5110 is a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices. It bines an advanced DSP feature set with a flexible, highperformance audio hub CODEC. The WM5110 digital core bines a quad-core, 600MMAC DSP system with a variety of power-efficient fixed-function audio processing blocks. 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. 110d B SNR, and noise levels as low as 2μVRMS, offer hi-fi quality line or headphone output. High power, high-quality speaker output is provided by a stereo pair of 2W Class-D speaker amplifiers. Four channels of stereo PDM output are provided, for connection to external amplifiers. The WM5110 supports up to eight microphone inputs, (up to six analogue, or up to eight PDM digital, or binations of each). Microphone activity detection with interrupt is available. A smart accessory interface supports most standard 3.5mm accessories. Impedance sensing and measurement is provided for external accessory and pushbutton...
