The WM5102 is a highly integrated, low power, digital core audio system that 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), or user-programmed solutions can also be supported. Fixed-function signal processing blocks include filters, EQ, dynamics processors and sample rate converters.
