2.1. Hardware Features
7.1+2 Channel High Definition Audio Codec
High-performance DACs with 103dB SNR are ideal for Dolby
ADCs with 90dBA SNR
Meets performance requirements for audio on PC2001 systems
10 DAC channels support 16/20/24-bit PCM format for 7.1 sound playback, plus 2 channels of
independent stereo sound output (multiple streaming) through the Front-Out-Left and
Front-Out-Right channels
3 stereo ADCs support 16/20-bit PCM format, two for microphone array, one for legacy mixer
recording
All DACs supports 44.1K/48K/96K/192kHz sample rate
All ADCs support 44.1K/48K/96K sample rate
Applicable for DVD-Audio solutions
16/20/24-bit S/PDIF-OUT supports 44.1K/48K/96/192kHz sample rate
16/20/24-bit S/PDIF-IN supports 44.1K/48K/96/192kHz sample rate
Up to four channels of microphone input are supported for AEC/BF application
High-quality analog differential CD input
Supports external PCBEEP input and built-in digital BEEP generator
Software selectable 2.5V/3.75V VREFOUT
Six VREFOUTs are supported by default, with additional four VREFOUTs available by sharing
unused analog I/O pins
Two jack detection pins each designed to detect up to 4 jacks
Reserve analog mixer architecture for backward compatibility with AC'97
Wide range (–80dB ~ +42dB) volume control with 1.5dB resolution of analog to analog mixer gain
All analog jacks are stereo input and output re-tasking for analog plug & play
Built-in headphone amplifiers for each re-tasking jack
Supports both analog DC volume control and GPI digital volume control
2 GPIOs (General Purpose Input/Output) for customized applications
Optional EAPD (External Amplifier Power Down) is supported
