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 I

2S, left justified, right

justified and DSP digital audio formats.

The device is controlled via a 3-wire serial interface. The

interface provides access to all features including volume

controls, mutes, de-emphasis and power management

facilities. A hardware control interface allows access to a

limited feature set. The WM8569 is available in a 28-lead

SSOP.
