24-bit 192kHz 2Vrms Multi-Channel CODEC  
DESCRIPTION  
FEATURES  
Multi-channel CODEC with 8 stereo input selector and 3  
stereo output selector  
The WM8593 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  
independent volume control and clocking, and a range of  
input/output channel selection options for flexible routing  
within current and future audio systems.  
4-channel DAC, 2-channel ADC  
8x2Vrms stereo input selector with 8x2 channel analogue  
bypass to output selector  
3x2Vrms stereo output selector  
Audio performance  
The WM8593 has an eight stereo input selector which  
accepts input levels up to 2Vrms. One stereo input can be  
routed to the ADC. All inputs can be routed to an output  
selector.

DAC: 100dB SNR typical (‘A’ weighted @ 48kHz)  
DAC: -90dB THD typical  
ADC: 100dB SNR typical (‘A’ weighted @ 48kHz)  
ADC: -90dB THD typical  
The output selector inputs two DAC channels and all  
analogue bypass inputs, and outputs three independent  
stereo channels at 2Vrms line level. The DAC channels  
include independent digital volume control, and all three  
output channels include analogue volume control.  
Independent sampling rate for ADC and DACs  
Independent sampling rate for DAC1 and DAC2  
DACs sampling frequency 32kHz – 192kHz  
ADC sampling frequency 32kHz – 96kHz  
DAC digital volume control +12dB to -100dB in 0.5dB  
steps  
The WM8593 is ideal for audio applications requiring high  
performance and flexible routing options, including flat panel  
digital TV and DVD recorder.  
ADC analogue volume control from +30dB to -97dB in  
0.5dB steps  
The WM8593 supports up to 2Vrms analogue inputs, 2Vrms  
outputs, with sample rates from 32kHz to 192kHz on the  
DACs, and 32kHz to 96kHz on the ADC.  
Output analogue volume control +6dB to -74dB in 0.5dB  
steps with zero cross or soft ramp to prevent pops and  
clicks  
The device is controlled via a serial interface with support  
for 2-wire and 3-wire control with readback. Control of mute,  
powerdown and reset can also be achieved by pin selection.  
Headphone drive capability on one stereo output with jack  
detect  
Digital multiplexer to interface to multiple digital sources –  
DSP, HDMI, memory card  
The WM8593 is available in a 64-lead TQFP package.  
2-wire and 3-wire serial control interface with readback and  
hardware reset, mute and powerdown pins  
Independent master or slave clocking modes  
Programmable format audio data interface modes
