Evaluation Board For Stereo Digital Audio Delay Processor
The TPA5052 evaluation module EVM consists of a single TPA5052 audio delay device, along with other external components mounted on a printed-circuit board PCB. It can be used to digitally delay both channels by up to 8191 samples with a 48 kHz sampling rate, that equates to more than 170 ms of delay.
The is designed so that analog music can be input to the board. The music is converted to I²S digital format where the TPA5052 delays it. The music is then converted back to analog where it is fed to the TPA4411 audio amplifier. The output of the TPA4411 is connected to a 3.5 mm stereo headphone jack. A simple pair of stereo headphones are all that are required to listen to the music. This allows the user to quickly and easily use the TPA5052EVM to delay the television audio to synchronize with the video.
