PRODUCTION DATA
The TFP401A-Q1 device is a digital visual interface (DVI)-compliant TMDS digital receiver 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. The host encodes the data and control signals 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 TFP401A-Q1 device 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 is then suitable for application directly to the flat-panel drive circuitry to produce an image on the display. Host and display separation distances can be up to 5 meters or more, making serial transmission of the pixel data preferable. Support of modern display resolutions up to UXGA requires a high-bandwidth receiver with good jitter and skew tolerance.
