WFN273_WM8593_AW.qxp 20/12/06 14:49 Page 1 WM8593, WM8594, WM8599 audio CODEC family for TV and DVD recorder WM8593 A complete audio solution for flat panel TV and DVD recorder WM8594 The WM8593, WM8594 and WM8599 are a new family of highly integrated single chip solutions for the audio routing, switching and conversion required in today’s digital TV or DVD-RW systems. WM8599 A unique system allows the user to route a wide range of analogue and digital audio signals through the device, whilst simultaneously utilising the two fully independent high performance stereo DACs and a stereo ADC. This means that one device can be the central routing point for all audio signals, both analogue and digital. 3 DACREFN DIGITAL AUDIO I/O ADC AND DAC DIGITAL I/O DACVMID 2 1 DACREFP MUTE /PWDN SDIN SCLK MODE /CS SDOUT /RESET ADCREFN ADCREFP AVDD1 ADCVMID AGND1 Every device in the family provides 2Vrms capable inputs and outputs allowing direct connection to external cables. The flexible input and output multiplexer allows any signal to be efficiently routed to any output, including a full analogue bypass. This provides a significant saving in PCB space and means that one core design can be quickly turned into multiple variants.

Audio performance AUDIO OUTPUTS I DAC: 100dB SNR -90dB THD typical I ADC: 100dB SNR -90dB THD typical Each CODEC has 3 outputs – capable of driving 2Vrms directly to the line and has an integrated headphone driver. Features like these reduce external component count and make an ideal solution for any multimedia system. Independent sampling rates for ADC and DACs 2 DAC 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: 0dB to -80dB All volume controls include zero cross detection to prevent pops and clicks 2-wire or 3-wire serial control interface with readback and hardware reset, mute and powerdown pins Master or slave clocking modes for digital audio interface DIGITAL AUDIO I S MULTIPLEXER In addition to the powerful analogue audio signal routing, the WM8593 can also act as the digital hub of a modern system. 2 Digital devices with I S inputs or outputs, such as HDMI receivers, surround sound DSPs, S/PDIF transceivers or additional DACs and ADCs can be routed to the Wolfson CODEC, making systems smaller and more scalable. This digital audio routing flexibility simplifies system design and allows use of a wider range of high quality system processors.
