TPA5051 Overview
The TPA5051 accepts two serial audio inputs, buffers the data for a selectable period of time, and outputs the delayed audio data on two serial outputs. One device allows delay of up to 85 ms/ch (fs = 48 kHz) to synchronize the audio stream to the video stream in systems with plex video processing algorithms. If more delay is needed, the devices can be connected in series.
