DisplayPort* is a digital communication interface that uses differential signaling to

achieve a high-bandwidth bus interface designed to support connections between PCs

and monitors, projectors, and TV displays. DisplayPort* is also suitable for display

connections between consumer electronics devices, such as high-definition optical disc

players, set top boxes, and TV displays.

A DisplayPort* consists of a Main Link, Auxiliary channel, and a Hot-Plug Detect signal.

The Main Link is a unidirectional, high-bandwidth, and low latency channel used for

transport of isochronous data streams such as uncompressed video and audio. The

Auxiliary Channel (AUX CH) is a half-duplex bidirectional channel used for link

management and device control. The Hot-Plug Detect (HPD) signal serves as an

interrupt request for the sink device.

The processor is designed in accordance with the VESA DisplayPort* Standard Version

1.2a. The processor supports VESA DisplayPort* PHY Compliance Test Specification

1.2a and VESA DisplayPort* Link Layer Compliance Test Specification 1.2a.

The High-Definition Multimedia Interface* (HDMI*) is provided for transmitting

uncompressed digital audio and video signals from DVD players, set-top boxes, and

other audiovisual sources to television sets, projectors, and other video displays. It

can carry high quality multi-channel audio data and all standard and high-definition

consumer electronics video formats. The HDMI display interface connecting the

processor and display devices uses transition minimized differential signaling (TMDS)

to carry audiovisual information through the same HDMI cable.

HDMI includes three separate communications channels: TMDS, DDC, and the optional

CEC (consumer electronics control). CEC is not supported on the processor. As shown

in the following figure, the HDMI cable carries four differential pairs that make up the
