Functional Architecture Intel® Workstation Board S5520SC TPS
Revision 1.7
Intel order number: E39530-010
48
3.13 Audio Codec
The workstation board supports the Intel
®
High Definition audio subsystem based on the
Realtek* ALC889 audio codex.
The feature list for the ALC889 is as follows:
High-performance DACs with 108dB signal-to-noise ratio (A-weighting)
High-performance ADCs with 104dB signal-to-noise ration (A-weighting)
Meets Microsoft* WLP3.0x and future WLP4.0 Premium audio requirements
Ten DAC channels support 16/20/24-bit PCM format for 7.1 sound playback plus two
channels of concurrent independent stereo sound output (multiple streaming) through
the front panel output
Three stereo ADCs support 16/20/24-bit PCM format, multiple stereo recording
All DACs support 44.1k/48k/88.2k/96k/192kHz sample rates
All ADCs support 44.1k/48k/88.2k/96k/192kHz sample rates
Primary 16/20/24-bit S/PDIF-OUT supports 32k/44.1k/48k/88.2k/96k/192kHz sample
rates
Supports 44.1k/48k/96kHz ADAT digital output (Pin shared with S/PDIF-OUT)
High-quality analog differential CD input
Supports external PCBEEP input and built-in digital BEEP generator
Up to four channels of microphone array input are supported for AEC/BF applications
Two jack detection pins, each designed to detect up to four plugged-in jacks
Supports analog GPIO2 for jack detection of CD input, which is used as a 9
th
analog port
Supports legacy analog mixer architecture
Three GPIOs (General Purpose Input and Output) for customized applications
Supports mono and stereo digital microphone interfaces (pins shared with GPIO0 and
GPIO1)
Hardware Zero-Detect output volume control
1 dB per step output volume and input volume control
The Intel
®
Workstation Board S5520SC provides one external audio connection through the rear
I/O and supports the following audio connections inside the chassis.
