2.2 Power Requirements

The TAS67CD-AEC requires multiple power inputs for operation. The TAS67CD-AEC power tree is shown in the below block diagram. IOVDD and VSYS5V0 are provided through the AEC connector from the host processor board. PVDD is provided through a set of banana plug receptacles and requires an external compatible DC supply be attached to the board.

The requirements for all of these power inputs are described in the table below. The IOVDD and VSYS5V0 requirements are compatible with the AM275-AUDIO-EVM and AM62D-AUDIO-EVM AEC interface implementations.
