Desktop Board Features

Audio Subsystem

The board supports Intel High Definition Audio through a Realtek ALC888S audio codec as well as through the HDMI interface.

The Realtek ALC888S-based audio subsystem provides the following features:

•Advanced jack sense for the back panel audio connectors that enables the audio codec to recognize the device that is connected to an audio port. The back panel audio connectors are capable of retasking according to the user’s definition, or can be automatically switched depending on the recognized device type.

•Stereo input and output via back panel connectors

•Headphone and Mic in functions for front panel audio connectors

•A signal-to-noise (S/N) ratio of 90 dB

The board provides onboard audio headers and back panel connectors. The onboard audio headers include the following:

•Front panel audio (a 2 x 5 pin header that provides headphone and mic in signals for front panel audio connectors)

•S/PDIF audio header (1 x 4 pin header)

•Internal mono speaker header (1 x 2 pin header)

Front panel headphone output is supported by a separate audio channel pair, allowing multi-streaming audio configurations such as simultaneous 6-channel (5.1) surround sound playback and stereo audio conferencing (through speakers connected to the back panel audio connectors and a headset connected to front panel audio connectors).

The onboard internal mono speaker header allows connection to an internal, low- power speaker for basic system sound capability. The subsystem is capable of driving a target speaker load of 8 Ω at 1 W (rms) or 4 Ω at 1.5 W (rms).

The onboard S/PDIF header allows connection to coaxial or optical adapters for digital audio output.

The back panel audio connectors are configurable through the audio device drivers. Audio software and drivers are available from http://downloadcenter.intel.com/.

LAN Subsystem

The LAN subsystem includes:

•Intel 82578DC Gigabit (10/100/1000 Mb/s) Ethernet LAN controller

•RJ-45 LAN connector with integrated status LEDs

LAN software and drivers are available at http://downloadcenter.intel.com/.

Two LEDs are built into the RJ-45 LAN connector located on the back panel (see Figure 2). These LEDs indicate the status of the LAN as shown in Table 3.
