13 AUDIO CODEC SUBSYSTEM

13.1 GENERAL DESCRIPTION

The WM8352 includes a high-performance stereo CODEC. Analogue output buffers and input

amplifiers are integrated on-chip, enabling the WM8352 to connect directly to headphones and

microphones as well as line-in and line-out sockets.

The CODEC handles analogue-to-digital and digital-to-analogue conversion for audio signals, and

integrates programmable filtering. Analogue mixing capabilities are also provided.

Digital audio data is transferred to and from the audio CODEC through a dedicated audio interface

that supports a number of industry-standard data formats.

Electrical power is provided to the CODEC through the following pins:



DBVDD and DGND – for the CODEC’s audio interface



DCVDD and DGND – for the CODEC’s digital core



HPVDD and HPGND – for the analogue outputs



AVDD and REF_GND – for ADC and DAC references



AVDD and GND – for all other analogue functions (including input amplifiers and buffers,

ADC, DAC, and analogue mixers)
