WM8599
24-bit 192kHz 2Vrms Multi-Channel CODEC
DESCRIPTION
FEATURES
The WM8599 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 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.
The WM8599 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.
The WM8599 outputs three stereo audio channels at line
levels up to 2Vrms, which can be selected from any of the
analogue inputs and DAC outputs. The DAC channels
include independent digital volume control, and all three
stereo output channels include analogue volume control
with soft ramp.
• Multi-channel CODEC with 5 stereo input selector and 3
stereo output selector
• 4-channel DAC, 2-channel ADC
• Five stereo 2Vrms stereo inputs with analogue bypass to
three stereo 2Vrms outputs
• Audio performance
- DAC: 100dB SNR typical (‘A’ weighted @ 48kHz)
- DAC: -90dB THD typical
- ADC: 100dB SNR typical (‘A’ weighted @ 48kHz)
- ADC: -90dB THD typical
• Independent sampling rates for ADC and DACs
• 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 WM8599 supports up to 2Vrms analogue inputs, 2Vrms
• All volume controls include zero cross detection to prevent
outputs, with sampling rates from 32kHz to 192kHz for the
pops and clicks
DACs, and 32kHz to 96kHz for the ADC.
• 2-wire serial control interface with readback and hardware
www.DataSheet4U.comreset, mute and powerdown pins
The WM8599 is ideal for audio applications requiring high
performance and flexible routing options, including flat panel
• Master or slave clocking modes
digital TV and DVD recorder.
• Programmable format audio data interface modes
The device is controlled via a serial interface with support
for 2-wire control with readback. Control of mute,
powerdown and reset can also be achieved by pin selection.
- I2S, LJ, RJ, DSP
• 3.3V / 9V analogue, 3.3V digital supply operation
• 48-lead TQFP package
The WM8599 is available in a 48-lead TQFP package.
APPLICATIONS
• Digital Flat Panel TV
• DVD-RW
