TPA5052评估模块（EVM）由一个单一的TPA5052音频延迟的装置，以及与其他外部元件安装在印刷电路板（PCB）上。该TPA5052EVM的设计，使模拟的音乐可以被输入到电路板上。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 TPA5052EVM 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 then is 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. Probe points also are provided.Additional evaluation may be performed with small modifications that allow for direct interaction with the TPA5052 in I2S format.
