DESCRIPTION
The TPA5050 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. One device allows delay of up to 170 ms/ch
(fs = 48 kHz) to synchronize the audio stream to the
video stream in systems with complex video
processing algorithms. If more delay is needed, the
devices can be connected in series.
