2.1.
7.1+2 Channel High Definition Audio Codec
w/Two Independent S/PDIF-OUT
High-performance DACs with 97dB SNR (A-Weighting), ADCs with 90dB SNR (A-Weighting)
Meets performance requirements for Microsoft WLP 3.10 Premium desktop and mobile PCs
Ten 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 panel output
Two stereo ADCs support 16/20-bit PCM format, one for stereo microphone, one for legacy mixer
recording
All DACs supports 44.1k/48k/96k/192kHz sample rate
All ADCs support 44.1k/48k/96k sample rate
Two independent 16/20/24-bit S/PDIF-OUT converters support 44.1k/48k/88.2k/96k/192kHz sample
rate, one for nominal digital audio, the other one for digital audio output to a HDMI transmitter
One 16/20/24-bit S/PDIF-IN converter supports 44.1k/48k/96k/192kHz sample rate
Up to four channels of analog microphone array input are supported for AEC/BF application
Supports stereo digital microphone interface for improved voice quality
High-quality analog differential CD input
Supports external PCBEEP input and built-in digital BEEP generator
Software selectable 2.5V/3.75V VREFOUT
Two jack detection pins each designed to detect up to 4 jacks
Supports legacy analog mixer architecture
Wide range (–80dB ~ +42dB) volume control with 1.5dB resolution of analog to analog mixer gain
Software selectable boost gain (+10/+20/+30dB) for analog microphone input
All analog jacks are stereo input and output re-tasking for analog plug & play
Built-in headphone amplifiers for each re-tasking jack
Two digital GPIOs (General Purpose Input and Output) and one analog GPIO (AGPIO) for
customized applications
