function, which provides support for next-
generation video display interface technology. The Video Electronics Standards Association (VESA)
defines the DisplayPort standard as an open digital communications interface for use in internal
connections such as:
• Interfaces within a PC or monitor
• External display connections, including interfaces between a PC and monitor or projector, between a
PC and TV, or between a device such as a DVD player and TV display
The Altera DisplayPort source has a scalable main link with 1, 2, or 4 lanes for a total up to 21.6 Gbps
bandwidth. A bidirectional AUX channel with 1 Mbps Manchester encoding provides side-band
communication. The sink uses a hot plug detect (HPD) signal to announce its presence, and the source
uses the same signal to initiate link configuration.

The main link has three selectable data rates: 1.62, 2.7, and 5.4 Gbps.
