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.

Evaluation board

TPA5051EVM — TPA5051 Evaluation Module (EVM)

The TPA5051 evaluation module (EVM) consists of a single TPA5051 audio delay device, along with other external components mounted on a printed-circuit board (PCB) that can be used to independently delay two digital audio streams. Each digital audio stream consists of a left and right channel, both (...)
