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.  
3.3 V Operation With 5 V Tolerant I/O  
Supports Audio Bit Clock Rates of 32 to 64 fs  
with fs = 32 kHz–192 kHz  
No External Crystal or Oscillator Required  
– All Internal Clocks Generated From the  
Audio Clock  
Surface Mount 4mm × 4mm, 16-pin QFN
