9.1 Overview

The TFP401/401A is a digital visual interface (DVI)-compliant TMDS digital receiver that is used in digital flat panel display systems to receive and decode TMDS-encoded RGB pixel data streams. In a digital display system a host, usually a PC or workstation, contains a TMDS-compatible 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, requires a TMDS-compatible receiver like the TI TFP401/401A 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. Because the host and display can be separated by distances up to 5 meters or more, serial transmission of the pixel data is preferred. To support modern display resolutions up to UXGA, a high-bandwidth receiver with good jitter and skew tolerance is required.
