Single Serial Input Port  
Delay Time: 170 ms/ch at fs = 48 kHz  
Delay Resolution: One Sample  
DESCRIPTION  
Delay Memory Cleared on Power-Up or After  
Delay Changes  
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.  
– Eliminates Erroneous Data From Being  
Output  
3.3 V Operation With 5 V Tolerant I/O and I2C  
Control  
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
