w WM5102S 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 combination 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...
