Kit Operation

5.2 Analog Output

The analog outputs from the TLV320AIC11xx are available on J1 (top or bottom). They also may be

accessed through J6 or J7.

5.3 Digital Control

The digital control signals can be applied directly to J4 and J5 (top or bottom side). The modular

TLV320AIC11xxEVM can also be connected directly to the USB-MODEVM Interface board included as

part of the TLV320AIC11xxEVM-K.

5.4 Default Jumper Locations

Table 5 lists the jumpers found on the EVM and their respective factory default conditions.

6 Kit Operation

This section provides information on using the TLV320AIC11xxEVM-K, including set up, program

installation, and program usage.

6.1 TLV320AIC11xxEVM-K Block Diagram

A block diagram of the TLV320AIC11xxEVM-K 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 TLV320AIC11xxEVM described previously in this manual.
