TLV320AIC3204EVM-K Setup and Installation

2.5.1

Stand-Alone Operation

When used as a stand-alone EVM, power is applied to P23/J23 directly, making sure to reference the

supplies to the appropriate grounds on that connector.

CAUTION

Verify that all power supplies are within the safe operating limits shown on the

TLV320AIC3204 data sheet before applying power to the EVM.

P23/J23 provides connection to the common power bus for the TLV320AIC3204EVM. Power is supplied

on the pins listed in Table 6.

The TLV320AIC3204EVM-K motherboard (the USB-MODEVM Interface board) supplies power to P23/J23

of the TLV320AIC3204EVM. Power for the motherboard is supplied either through its USB connection or

via terminal blocks on that board.

2.5.2

USB-MODEVM Operation

The USB-MODEVM Interface board can be powered from several different sources:

•

USB

•

6-Vdc to 10-Vdc AC/DC external wall supply (not included)

•

Laboratory power supply

When powered from the USB connection, JMP6 must have a shunt from pins 1–2 (this is the default

factory configuration). When powered from 6-Vdc to 10-Vdc power supply, either through the J8 terminal

block or J9 barrel jack, JMP6 must have a shunt installed on pins 2–3. If power is applied in any of these

ways, onboard regulators generate the required supply voltages, and no further power supplies are

necessary.

If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM Interface,

JMP6 must have no shunt installed. Voltages are then applied to J2 (+5VA), J3 (+5VD), J4 (+1.8VD), and

J5 (+3.3VD). The +1.8VD and +3.3VD can also be generated on the board by the onboard regulators from

the +5VD supply; to enable this configuration, the switches on SW1 need to be set to enable the

regulators by placing them in the ON position (lower position, looking at the board with text reading right-

side up). If +1.8VD and +3.3VD are supplied externally, disable the onboard regulators by placing SW1

switches in the OFF position.

Each power supply voltage has an LED (D1-D7) that illuminates when the power supplies are active.

TLV320AIC3204EVM-K Setup and Installation

The following section provides information on using the TLV320AIC3204EVM-K, including setup, program

installation, and program usage.

NOTE:

If using the EVM in stand-alone mode, the software must be installed per the following

instructions, but the hardware configuration may be different.

3.1

Software Installation

1. Download the latest version of the AIC3204 Control Software (CS) located in the

TLV320AIC3204EVM-K Product Folder.

2. Open the self-extracting installation file.

3. Extract the software to a known folder.

4. Install the EVM software by double-clicking the Setup executable, and follow the directions. The user

may be prompted to restart their computer.

This installs all the TLV320AIC3204EVM-K software and required drivers onto the PC.
