Default

Jumper Position Jumper Description

JMP15 Installed When installed, shorts across the output capacitor on HPROUT; remove this jumper if using AC-coupled output drive

JMP16 Installed When installed, shorts HPLCOM and HPRCOM. Use only if these signals are set to constant VCM.

JMP17 Installed When installed, shorts across the output capacitor on HPRCOM; remove this jumper if using AC-coupled output drive

JMP18 Open Selects on-board EEPROM as Firmware Source.

JMP19 Open When installed, allows the USB-MODEVM to hardware reset the device under user control

2.3 Analog Signal Connections

2.3.1 Analog Inputs

The analog inputs to the EVM can be connected through two different methods.The analog input sources

can be applied directly to J13 (top or bottom side) or through the analog headers (J1-3 and J6) around the

edge of the board. The connection details of each header/connector can be found in Appendix A.

2.3.2 Analog Output

The analog outputs to the EVM can be connected through two different methods. The analog outputs are

available from the J13 and J14 (top or bottom) or they may be accessed through J4, J5, J7, J11,and J12

at the edges of the board. The connection details can be found in Appendix A.

2.4 Digital Signal Connections

2.4.1 Digital Inputs and Outputs

The digital inputs and outputs of the EVM can be monitored through J16 and J17. If external signals need

to be connected to the EVM, digital inputs should be connected via J14 and J15 on the USB-MODEVM

and the SW2 switch should be changed accordly (see Section 2.2.1). The connector details are available

in Section A.2.

2.4.2 Digital Controls

The digital control signals can be applied directly to J16 and J17 (top or bottom side). The modular

TLV320AIC3106EVM can also be connected directly to a DSP interface board, such as the

5-6KINTERFACE or HPA-MCUINTERFACE, or to the USB-MODEVM Interface board if purchased as part

of the TLV320AIC3106EVM-PDK. See the product folder for this EVM or the TLV320AIC3106 for a current

list of compatible interface and/or accessory boards.

2.5 Power Connections

The TLV320AIC3106EVM can be powered independently when being used in stand-along operation or by

the USB-MODEVM when it is plugged onto the motherboard.
