WM5102S Datasheet | Wolfson Microelectronics

w Audio Hub CODEC with Master Hi-Fi DSP DESCRIPTION The WM5102S[1] is a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices. It supports audiophile quality DAC playback on a flexible, high-performance audio hub. The WM5102S digital core provides a powerful bination of fixed-function signal processing blocks with a programmable DSP. These are supported by a fully-flexible, all-digital audio mixing and routing engine with sample rate converters, for wide use-case flexibility. The programmable DSP supports a range of audio processing software packages, including user-programmed solutions. A suite of signal processing software packages is licensed as part of the WM5102S product, though different audio algorithms can also be implemented. Fixed-function signal processing blocks include filters, EQ, dynamics processors and sample rate converters. 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. Two stereo headphone drivers each provide stereo groundreferenced or mono BTL outputs, with noise levels as low as 1µVRMS (HPOUT1) for hi-fi quality line or headphone output. The CODEC also Features stereo 2W Class-D speaker outputs, a dedicated BTL earpiece output and PDM for external speaker amplifiers. A signal generator for controlling haptics devices is included; vibe actuators can connect directly to the Class-D speaker output, or via an external driver on the PDM output interface. All inputs, outputs and system interfaces can function concurrently. The WM5102S supports up to six microphone inputs, each either analogue or PDM digital. Microphone activity detection with...
