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.
