The TPA5052 accepts a single serial audio input, buffers the data for a selectable period of time, and outputs the delayed audio data on a single serial output. In systems with complex video processing algorithms, one device allows delay of up to 170 ms/ch (fs = 48 kHz) to synchronize the audio stream to the video stream. If more delay is needed, the devices can be connected in series.
