DESCRIPTION

The WM8569 is a stereo audio codec ideal for DVD, PVR, LCD-TV and automotive applications. Independent ADC and DAC clocking permits separate record and playback sampling rates.

A stereo 24-bit multi-bit sigma delta DAC with oversampling and digital interpolation filters provides the output signal. Digital audio input word lengths from 16-24 bits and sampling rates from 8kHz to 192kHz are supported.

A stereo 24-bit multi-bit sigma delta ADC is used. Digital audio output word lengths from 16-24 bits and sampling rates from 32kHz to 96kHz are supported. The DAC and ADC support independent sampling rates.

The audio data interface supports I2S, left justified, right justified and DSP digital audio formats.
