DESCRIPTION
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.
