The TPA5051 evaluation module (EVM) consists of a single TPA5051 audio delay device, along with other external components mounted on a printed-circuit board (PCB) that can be used to independently delay two digital audio streams. Each digital audio stream consists of a left and right channel, both of which can be delayed up to 4095 samples (with a 48-kHz sampling rate, that equates to more than 85ms of delay). The TPA5051EVM is designed to work seamlessly with the TI Input USB board, but can function as a stand-alone board for pass-through testing in any system. All that is required is an I 2 S audio source, an I 2 C controller, and a 5-V supply.
