WM8580A w Multichannel CODEC with S/PDIF Transceiver DESCRIPTION FEATURES Multi-channel CODEC with 3 Stereo DACs and 1 Stereo The WM8580A is a multi-channel audio CODEC with ADC S/PDIF transceiver. The WM8580A is ideal for DVD and surround sound processing applications for home hi-fi, Integrated S/PDIF / IEC-60958-3 transceiver automotive and other audiovisual equipment. Audio Performance 103dB SNR (A weighted 48kHz) DAC Integrated into the device is a stereo 24-bit multi-bit sigma delta ADC with support for digital audio output word lengths -90dB THD (48kHz) DAC from 16-bit to 32-bit, and sampling rates from 8kHz to 100dB SNR (A weighted 48kHz) ADC 192kHz. -87dB THD (48kHz) ADC Also included are three stereo 24-bit multi-bit sigma delta DAC Sampling Frequency: 8kHz 192kHz DACs, each with a dedicated oversampling digital ADC Sampling Frequency: 8kHz 192kHz interpolation filter. Digital audio input word lengths from 16- Independent ADC and DAC Sample Rates bits to 32-bits and sampling rates from 8kHz to 192kHz are 2 and 3-Wire Serial Control Interface with readback, or supported. Each DAC channel has independent digital Hardware Control Interface volume and mute control. GPO pins allow visibility of user selected status flags 2 Two independent audio data interfaces support I S, Left Programmable Audio Data Interface Modes Justified, Right Justified and DSP digital audio formats. 2 I S, Left, Right Justified or DSP Each audio interface can operate in either Master Mode or 16/20/24/32 bit Word Lengths Slave Mode. Three Independent Stereo DAC Outputs with Digital The S/PDIF transceiver is IEC-60958-3 compatible and Volume Controls supports frame rates from 32k/s to 96k/s. It has four Two Independent Master or Slave Audio Data Interfaces multiplexed inputs and one output. Status and error Flexible Digital Interface Routing with Clock Selection monitoring is built-in and results can reported over the serial Control interface or via GPO pins. S/PDIF Channel Block configuration is also supported. 2.7V to 5.5V Analogue, 2.7V to 3.6V Digital Supply Operation The device has two PLLs that can be configured 48-lead TQFP Package independently to generate two system clocks for internal or external use. Device control and setup is via a 2-wire or 3-wire (SPI APPLICATIONS compatible) serial interface. The serial interface provides access to all features including channel selection, volume Digital TV controls, mutes, de-emphasis, S/PDIF control/status, and DVD Players and Receivers Surround Sound AV Processors and Hi-Fi systems power management facilities. Alternatively, the device has a Hardware Control Mode where device features can be Automotive Audio enabled/disabled using selected pins. The device is available in a 48-lead TQFP package.
