Kit Operation
The following section provides information on using the TLV320DAC32EVM-PDK, including set up,
program installation, and program usage.
A block diagram of the TLV320DAC32EVM-PDK is shown in Figure 1 . The evaluation kit consists of two
circuit boards connected together. The motherboard is designated as the USB-MODEVM Interface board,
while the daughtercard is the TLV320DAC32EVM described previously in this manual.
Figure 1. TLV320DAC32EVM-PDK Block Diagram
The USB-MODEVM Interface board is intended to be used in USB mode, where control of the installed
EVM is accomplished using the onboard USB controller device. However, a provision is made for driving
all the data buses (I

C, SPI™, I

S/AC97) externally. The source of these signals is controlled by SW2 on
the USB-MODEVM. See Table 6 for details on the switch settings.
