The TAS67CD-AEC EVM is intended to expand on compatible TI Audio DSP EVMs. The Audio Expansion Connector (AEC) enables up to eight channels of 50W amplified digital audio output using two TAS6754-Q1 devices. The Audio DSP EVM uses I2C through the AEC to manage the TAS67 devices. Digital audio data is sent to the TAS67 devices using the MCASP peripheral of the SOC on the Audio DSP EVM.
An external power supply is needed to power the TAS67 devices and the PVDD and VBAT power rails. The allowed input range for PVDD and VBAT is 4.25V to 18.5V, with a maximum current draw of 11A.
Figure 2-1 shows the complete block diagram for the TAS67CD-AEC.
