About DVI–General Description  

The Digital Visual Interface (DVI) is a video interface standard covering the 
transmission of video between a source device (such as a personal computer) and 
a display device. DVI is designed to carry uncompressed digital video data to a 
display. It is partially compatible with the HDMI (High-Definition Multimedia 
Interface) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).  

A single-link DVI connection consists of four TMDS links; each link transmits data 
from the source to the device over 1 twisted wire pair. Three of the links 
correspond to the RGB components of the video signal: red, green, blue (for a 
total of 24 bits per pixel.) The fourth link carries the pixel clock. Each TMDS link 
carries binary data at ten times the pixel clock reference frequency, for a 
maximum data rate of 1.65Gbps × 3 data pairs for single-link DVI. 

The DVI specification mandates a maximum pixel clock frequency of 165MHz 
when running in single-link mode. With a single DVI link, the highest supported
