1 Introduction
1.1 Description
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
I C controller, and a 5-V supply.
The TPA5051EVM also includes an onboard digital-to-analog controller (DAC), the PCM1606, which can
2
convert I S or left-justified data to an analog out. The analog out is filtered on the board and can be
viewed with a scope probe.
