WM8594

24-bit 192kHz 2Vrms Multi-Channel CODEC

DESCRIPTION

FEATURES

•

Multi-channel CODEC with 5 stereo input selector and 3

stereo output selector

The WM8594 is a high performance multi-channel audio

CODEC with flexible input/output selection and digital and

analogue volume control. Features include a 24-bit stereo

ADC with digital gain control, two 24-bit DACs with

•

4-channel DAC, 2-channel ADC

Five stereo 2Vrms stereo inputs with analogue bypass to

three stereo 2Vrms outputs

independent digital volume control, and

a range of

input/output channel selection options with analogue volume

control, for flexible routing within current and future audio

systems.

•

Stereo headphone driver

Audio performance

DAC: 100dB SNR typical (‘A’ weighted @ 48kHz)

DAC: -90dB THD typical

The WM8594 accepts five stereo audio inputs at line levels

up to 2Vrms. One stereo input can be routed to the ADC. All

inputs can be routed to the output.

ADC: 100dB SNR typical (‘A’ weighted @ 48kHz)

ADC: -90dB THD typical

The WM8594 outputs three stereo audio channels at line

levels up to 2Vrms, which can be selected from any of the

analogue inputs and DAC outputs. Additionally, one stereo

output is available with a headphone driver. The DAC

channels include independent digital volume control, and all

three stereo output channels include analogue volume

control with soft ramp.

•

Independent sampling rates for ADC, DAC1 and DAC2

DACs sampling frequency 32kHz to 192kHz

ADC sampling frequency 32kHz to 96kHz

ADC digital gain control: +30dB to -97dB

DAC digital volume control: +12dB to -100dB

Analogue Volume control with soft ramp: +6dB to -73.5dB

The WM8594 supports up to 2Vrms analogue inputs, 2Vrms

outputs, with sampling rates from 32kHz to 192kHz for the

DACs, and 32kHz to 96kHz for the ADC.

All volume controls include zero cross detection to prevent

pops and clicks

•

2 and 3-wire serial control interface with readback and

hardware reset, mute and powerdown pins

The WM8594 is ideal for audio applications requiring high

performance and flexible routing options, including flat panel

digital TV and DVD recorder.

•

Master or slave clocking modes

Programmable format audio data interface modes

I²S, LJ, RJ, DSP

The device is controlled via a serial interface with support

for 2-wire and 3-wire control with full readback. Control of

mute, powerdown and reset can also be achieved by pin

selection.

•

3.3V / 9V analogue, 3.3V digital supply operation

48-lead TQFP package

The WM8594 is available in a 48-lead TQFP package.

APPLICATIONS

•

Digital Flat Panel TV

DVD-RW
