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.
