WM8569

24-bit, 192kHz Stereo CODEC with Volume Control

DESCRIPTION

FEATURES

•

Audio Performance

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.

−

103dB SNR (‘A’ weighted @ 48kHz) DAC

DAC Sampling Frequency: 8kHz – 192kHz

100dB SNR (‘A’ weighted @ 48kHz) ADC

ADC Sampling Frequency: 32kHz – 96kHz

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.

•

Independent Sampling Rates for ADC and DAC

3-wire SPI Serial or Hardware Control Interface

Audio Mute and De-Emphasis Functions

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.

Programmable Audio Data Interface Modes

−

16/20/24/32 bit Word Lengths

I²S, Left, Right Justified or DSP

•

2.7V to 5.5V Analogue Supply

2.7V to 3.6V Digital Supply

28-lead SSOP Package

The audio data interface supports I²S, 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.

APPLICATIONS

•

DVD Recorder

Personal Video Recorder

PC Sound Card

Automotive Audio

LCD-TV
