Product Summary

The TPA5050RSAR is a stereo digital audio lip-sync delay with I2C control. The TPA5050RSAR 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. The applications of the TPA5050RSAR include High Definition TV Lip-Sync Delay, Flat Panel TV Lip-Sync Delay, Home Theater Rear-Channel Effects, Wireless Speaker Front-Channel Synchronization.
