Product Overview

The TPA5050RSAR is a Stereo Digital Audio Delay Processor with I²C control 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 170ms/ch (fs=48kHz) 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.
  • 16 to 24bit I²S, Right-justified, left-justified digital audio formats
  • I²C bus controlled
  • Single serial input port
  • Delay memory cleared on power-up or after delay changes
  • Supports audio bit clock rates of 32 to 64fs with fs=32 to 192kHz
  • No external crystal or oscillator required
  • All internal clocks generated from the audio clock
  • Green product and no Sb/Br
