DESCRIPTION
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 complex video processing
algorithms. If more delay is needed, the devices can
be connected in series. Independent clocks can be
used for each audio input.
