Overview
The TPA5050RSAR is a Stereo Digital Audio Delay Processor produced by Texas Instruments. This component is designed to synchronize audio streams with video streams in various audio-visual systems. It accepts a single serial audio input, buffers the data for a selectable period, and outputs the delayed audio data on a single serial output. The device is particularly useful in applications requiring lip-sync delay adjustments, such as high-definition TVs, flat-panel TVs, home theaters, and wireless speakers.
