1.1 Introduction

The TAS67CD-AEC add-on card was developed to enable prototyping of multi-channel digital audio systems based on the TAS6754-Q1 4-channel Class-D amplifier and TI AM275x and AM62Dx families of processors. The TAS67CD-AEC implements the TI Audio Expansion Connector (AEC) interface available on audio baseboard EVM such as the AUDIO-AM275-EVM and AUDIO-AM62D-EVM.

With audio baseboard EVM providing two AEC interfaces, this enables creating 16-channel amplified audio systems. Combined with the audio baseboard EVM's onboard audio ADC, DAC and networking resources, the combined audio EVM system can be used to prototype a range of networked audio systems typical of automotive, in-vehicle, installations and industry standard surround sound topologies.

This user's guide describes how to properly use the add-on card with the audio baseboard EVM. This user's guide also details many important aspects of the add-on board including but not limited to power tree description, signal pathways, pin header descriptions, test points, and selectable switch settings.

Please see the TAS67CD-AEC tools page for schematics, bill of materials and PCB design files for this add-on card.
