WM5102

w WM5102 Audio Hub CODEC with Voice Processor DSP DESCRIPTION The WM5102[1] is a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices. It combines wideband telephony voice processing with a flexible, high-performance audio hub CODEC. The WM5102 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 (supplied separately); user-programmed solutions can also be supported. 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 2.3μVRMS 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 ampli...
