Interfaces
The processor HDMI interface is designed in accordance with the High-Definition
Multimedia Interface.
2.5.6 Digital Video Interface (DVI)
The processor Digital Ports can be configured to drive DVI-D. DVI uses TMDS for
transmitting data from the transmitter to the receiver, which is similar to the HDMI
protocol except for the audio and CEC. Refer to the HDMI section for more information
on the signals and data transmission. The digital display data signals driven natively
through the processor are AC coupled and need level shifting to convert the AC coupled
signals to the HDMI compliant digital signals.
2.5.7 embedded DisplayPort* (eDP*)
The embedded DisplayPort* (eDP*) is an embedded version of the DisplayPort
standard oriented towards applications such as notebook and All-In-One PCs. Like
DisplayPort, embedded DisplayPort* also consists of a Main Link, Auxiliary channel, and
an optional Hot-Plug Detect signal. eDP* can be bifurcated in order to support VGA
display.
2.5.8 Integrated Audio
• HDMI* and display port interfaces carry audio along with video.
• The processor supports 3 High Definition audio streams on 3 digital ports
simultaneously (the DMA controllers are in PCH).
• The integrated audio processing (DSP) is performed by the PCH, and delivered to
the processor using the AUDIO_SDI and AUDIO_CLK inputs pins.
• AUDIO_SDO output pin is used to carry responses back to the PCH
• Supports only the internal HDMI and DP CODECs.
