10 Applications and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

The TFP401 is a DVI (Digital Visual Interface) compliant digital receiver that is used in digital flat panel display

systems to receive and decode TMDS encoded RGB pixel data streams. A digital display system a host, usually

a PC or workstation, contains a DVI compliant transmitter that receives 24-bit pixel data along with appropriate

control signals and encodes them into a high-speed low voltage differential serial bit stream fit for transmission

over a twisted-pair cable to a display device. The display device, usually a flat-panel monitor, will require a DVI

compliant receiver like the TI TFP401 to decode the serial bit stream back to the same 24-bit pixel data and

control signals that originated at the host. This decoded data can then be applied directly to the flat panel drive

circuitry to produce an image on the display. Since the host and display can be separated by distances up to 5

meters or more, serial transmission of the pixel data is preferred. The TFP401 will support resolutions up to

UXGA.
