EVM Description and Basics
This section provides information on the analog input and output, digital control, power, and general
connection of the TLV320AIC3204EVM.
2.1
TLV320AIC3204EVM-K Block Diagram
The TLV320AIC3204EVM-K consists of two separate circuit boards, the USB-MODEVM and the
TLV320AIC3204EVM. The USB-MODEVM is built around the TAS1020B streaming audio USB controller
with an 8051-based core. The motherboard features two positions for modular EVMs, or one double-wide
serial modular EVM can be installed. The TLV320AIC3204EVM is one of the double-wide modular EVMs
that is designed to work with the USB-MODEVM.
The simple diagram of Figure 1 shows how the TLV320AIC3204EVM is connected to the USB-MODEVM.
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. Provision is made, however, for driving all
the data buses ( I2C™, SPI™, I2S, etc.) externally. The source of these signals is controlled by SW2 on
the USB-MODEVM. See Table 1 for details on the switch settings.
The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation module
or one larger evaluation module. The TLV320AIC3204EVM is designed to fit over both of the smaller
evaluation module slots as shown in Figure 1

TLV320AIC3204EVM-K Setup and Installation
www.ti.com
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 rightside 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.

EVM Connections
1. Ensure that the TLV320AIC3204EVM is installed on the USB-MODEVM Interface board, aligning J11,
J12, J21, J22, and J23 with the corresponding connectors on the USB-MODEVM.
2. Verify that the jumpers and switches are in their default conditions.
3. Attach a USB cable from the PC to the USB-MODEVM Interface board. The default configuration
provides power, control signals, and streaming audio via the USB interface from the PC. On the USBMODEVM, LEDs D3, D4, D5, and D7 illuminate to indicate that the USB is supplying power.
4. For the first connection, the PC recognizes new hardware and begins an initialization process. The
user may be prompted to identify the location of the drivers or allow the PC to automatically search for
them. Allow the automatic detection option.
5. Once the PC confirms that the hardware is operational, D2 on the USB-MODEVM illuminates to
indicate that the firmware has been loaded and the EVM is ready for use. If D2 does not illuminate,
verify that the EEPROM jumper and switch settings conform to Table 1 and Table 2.
After the TLV320AIC3204EVM-K software installation (described in Section 3.2) is complete, evaluation
and development with the TLV320AIC3204 can begin.

Adaptive Filtering
The TLV320AIC3204 features double-buffered filter coefficients which allow real-time filtering. The
TLV320AIC3204 features up to six cascaded biquads and a first-order IIR filter per DAC channel in
various signal processing blocks.
The Parametric Equalizer tab (shown in Figure 9) allows the user to modify the frequency response of the
digital input signal that is fed afterwards into the DAC channels. This application can be useful to fine-tune
the audio frequency response for a particular small speaker and enclosure system combination. The
processing block PRB_P2 (which is used for this application) has one IIR filter and six biquads in cascade
per audio channel. The first biquad (BQ0) is configured as a gain control which provides headroom and
compensation gain to the subsequent biquads in the cascade. Biquads BQ1 to BQ5 are configured for EQ
and/or shelf filters.
The Gain Q (quality) and fc (center frequency) parameters are available for the EQ filters whereas Gain
fc (corner frequency) and Shelf Response are available for the shelf filters. These parameters can be
modified using their corresponding control. Also, by dragging a cursor in the frequency response window,
the gain and fc for each biquad can be modified.
The PRB_P2 biquad coefficients are defined as 1.23, 2s complement format. Coefficients that are equal or
larger than unity must be normalized to comply with such format when converting from decimal format.
This can be achieved by dividing all numerators of a biquad by a scale factor equal to the largest
numerator divided by 223 minus one (if the numerator is equal or larger than unity). Normalization results in
an attenuated version of the same frequency response curve. The scale factor can then be used to
compensate for the attenuation at another unused biquad.

Automatic Gain Control
The left-channel Automatic Gain Control (AGC) can be enabled by checking the Enable Left AGC box
(Figure 10). Pressing the Capture Audio button records the left-channel audio. Its corresponding data is
displayed in the audio capture graph window. The small white window located at the bottom right of the
AGC tab displays the audio waveform of the recorded data. Ensure that the AIC32x4 EVM is selected as
the computer's default audio capture device before pressing this button. To set the TLV320AIC3204EVMK as the default audio device, open the Windows Control Panel → Sounds and Audio Devices Properties
and set the AIC32x4 EVM as the default audio recording device. Also, do not use any other media player
or audio recording software while the control software is recording.
The target level and noise threshold parameters can be modified by dragging the horizontal cursor lines
located at the audio capture graph window. Its numeric values are displayed to the right of the graph.
Noise threshold can be disabled by unchecking the Enable Noise Threshold box. The AGC Max Gain
control sets the maximum allowed AGC PGA Gain. The AGC Gain indicator bar continuously displays the
contents of Page 0/Register 93 if the Enable Polling box is checked.
Other parameters can be accessed by checking the Advanced? box. For more information about AGC,
see the Information tab and the data sheet.
Other flags related to this feature can be accessed at the Status Flags panel.

Dynamic Range Compression
Dynamic Range Compression (DRC) can be enabled by checking the Enable Left DRC and Enable
Right DRC boxes.
The level transfer characteristic graph is a function of the applied digital gain and the threshold parameter.
The graph line is separated into two piece-wise linear regions where the red line represents the level
range in which the DRC attenuation takes place, and the green line represents the level range in which
the signal is not affected by DRC. As an example, setting the threshold to -24 dB with a gain to 24 dB
implies that an input signal strength variation from -48 dB (threshold - gain) to 0 dB results in an output
signal strength variation from -24 dB to 0 dB, or a compression ratio of 2:1. Similarly, a threshold of -3 dB
with a gain of 24 dB implies that an input signal strength variation from -27 dB to 0 dB results in an output
signal strength variation from -3 dB to 0 dB, or a ratio of 9:1. Note that a gain less than 0 dB does not
result in expansion.
The Attack and Decay are time domain parameters that control the rate in which the applied gain reaches
the target gain after the threshold level is crossed. As an example, a fast attack rate quickly reaches the
target gain once the output signal crosses the programmed threshold region.
Other flags related to this feature can be accessed at the Status Flags panel.

Headset Detection
The TLV320AIC3204EVM provides two terminal blocks (J8 and J4) that can be used to connect different
types of cellular headset jacks. For proper headset detection, the jack connections must comply with the
figure shown in the Headset Detection section of the datasheet.
The Headset Detection panel provides hardware setup information for a four-conductor stereo + cellular
jack, as seen in Figure 12.
As an example, if stereo headphones are connected to the four-conductor jack, the tip and ring carry the
AC-coupled HPL and HPR signal to the headphone speakers whereas the shield shorts the SCLK/MFP3
pin to ground. This results in a stereo headset detection.
Checking the Enable Polling box displays the headset type at the Headset Type Detected box.
Other flags related to this feature can be accessed at the Status Flags panel.

DC Measurement
Terminal block J3 on the TLV320AIC3204EVM can be used to evaluate the DC measurement feature.
The Information tab provides the hardware setup information.
The Left ADC (V) and Right ADC (V) boxes convert the register data to voltage. The voltage is derived
from the References shown at the upper right corner of the DC Measurement tab. The DC measurement
register data is in 2.22, 2s complement format.

Control Categories
The Digital Settings, Analog Settings, and Signal Processing categories provide control of many
registers and other features of the TLV320AIC3204 . These categories are intended for the advanced
user. Hovering the mouse cursor on top of a control displays a tip strip that contains page, register, and bit
information. As an example, hovering on top of IN1_R of the Audio Inputs panel, as shown in Figure 14
displays p1_r55_b7-6 which means that this control writes to Page 1/Register 55/Bits D7 to D6.

controls update their status with respect to the register contents in the following conditions:
A panel is opened.
The Execute Command Buffer button in the Command-Line Interface is pressed.
The Refresh button at the bottom right of a panel is pressed.
Status Flags Panel
The TLV320AIC3204 status flags can monitored in the Status Flags panel (Figure 15) which is located
below the Panel Selection Tree . Pressing the POLL button continuously reads all the registers relevant
to each flag and updates those flags accordingly. The rate at which the registers are read can be modified
by changing the value in the Polling Interval numeric control. Note that a smaller interval reduces
responsiveness of other controls, especially volume sliders, due to bandwidth limitations. By default, the
polling interval is 200 ms and can be set to a minimum of 20 ms.
The Sticky Flags tab contains indicators whose corresponding register contents clear every time a read is
performed to that register. To read all the sticky flags, click the Read Sticky Flags button.

Command-Line Interface Panel
The Command-Line Interface panel provides a means to communicate with the TLV320AIC3204 using a
simple scripting language (described in Section G.3). The TAS1020B USB Controller (located on the USBMODEVM motherboard) handles all communication between the PC and the TLV320AIC3204.
A script is loaded into the command buffer, either by loading a script file using the File menu or by pasting
text from the clipboard using the Ctrl-V key combination (Figure 17).
When the command buffer is executed, the return data packets which result from each individual
command are displayed in the Command History control. This control is an array (with a maximum size
of 100 elements) that contains information about each command as well as status. The Interface box
displays the interface used for a particular command in the Command History array. The Command box
displays the type of command executed (i.e., write, read) for a particular interface. The Flag Retries box
displays the number of read iterations performed by a Wait for Flag command (see Section G.3 for
details). The Register Data array displays the register number and data bytes that correspond to a
particular command.
The Information tab provides additional information related to the Command History as well as
additional settings. The Syntax and Examples tabs provide useful information related to the scripting
language.
The File menu provides some options for working with scripts. The first option, Open Script File..., loads a
command file script into the command buffer. This script can then be executed by pressing the Execute
Command Buffer button. The contents of the Command Buffer can be saved using the Save Script
File... option.
Both the Command Buffer and Command History can be cleared by clicking their corresponding Clear
buttons.

Appendix G USB-MODEVM Protocol
G.1
USB-MODEVM Protocol
The USB-MODEVM is defined to be a Vendor-Specific class and is identified on the PC system as an NIVISA device. Because the TAS1020B has several routines in its ROM which are designed for use with
HID-class devices, HID-like structures are used, even though the USB-MODEVM is not an HID-class
device. Data is passed from the PC to the TAS1020B using the control endpoint.
Data is sent in a HIDSETREPORT (see Table 9).

The USB-MODEVM has seven GPIO lines. Access them by specifying the interface to be 0x08, and then
using the standard format for packets—but addresses are unnecessary. The GPIO lines are mapped into

Writing Scripts
A script is simply a text file that contains data to send to the serial control buses.
Each line in a script file is one command. No provision is made for extending lines beyond one line, except
for the > command. A line is terminated by a carriage return.
The first character of a line is the command. Commands are:
I Set interface bus to use
r Read from the serial control bus
w Write to the serial control bus
> Extend repeated write commands to lines below a w
# Comment
b Break
d Delay
f
Wait for Flag

Writing Scripts
www.ti.com
The first command, I, sets the interface to use for the commands to follow. This command must be
followed by one of the following parameters:
i2cstd
i2cfast
spi8
spi16
gpio
Standard mode I2C bus
Fast mode I2C bus
SPI bus with 8-bit register addressing
SPI bus with 16-bit register addressing
Use the USB-MODEVM GPIO capability
For example, if a fast mode I2C bus is to be used, the script begins with:
I i2cfast
A double quoted string of characters following the b command can be added to provide information to the
user about each breakpoint. When the script is executed, the software's command handler halts as soon
as a breakpoint is detected and displays the string of characters within the double quotes.
The Wait for Flag command, f, reads a specified register and verifies if the bitmap provided with the
command matches the data being read. If the data does not match, the command handler retries for up to
200 times. This feature is useful when switching buffers in parts that support the adaptive filtering mode.
The command f syntax follows:
f [i2c address] [register] [D7][D6][D5][D4][D3][D2][D1][D0] where 'i2c address' and 'register'
are in hexadecimal format and 'D7' through 'D0' are in binary format with values of 0, 1 or X for
don't care.
Anything following a comment command # is ignored by the parser, provided that it is on the same line.
The delay command d allows the user to specify a time, in milliseconds, that the script pauses before
proceeding. The delay time is entered in decimal format.
A series of byte values follows either a read or write command. Each byte value is expressed in
hexadecimal, and each byte must be separated by a space. Commands are interpreted and sent to the
TAS1020B by the program using the protocol described in Section G.1.
The first byte following an r (read) or w (write) command is the I2C slave address of the device (if I2C is
used) or the first data byte to write (if SPI is used—note that SPI interfaces are not standardized on
protocols, so the meaning of this byte varies with the device being addressed on the SPI bus). The
second byte is the starting register address that data will be written to (again, with I2C; SPI varies—see
Section G.1 for additional information about what variations may be necessary for a particular SPI mode).
Following these two bytes are data, if writing; if reading, the third byte value is the number of bytes to
read, (expressed in hexadecimal).
For example, to write the values 0xAA 0x55 to an I2C device with a slave address of 0x30, starting at a
register address of 0x03, the user writes:
#example script I i2cfast w 30 03 AA 55 r 30 03 02
This script begins with a comment, specifies that a fast I2C bus will be used, then writes 0xAA 0x55 to the
I2C slave device at address 0x30, writing the values into registers 0x03 and 0x04. The script then reads
back two bytes from the same device starting at register address 0x03. Note that the slave device value
does not change. It is unnecessary to set the R/W bit for I2C devices in the script; the read or write
commands does that.
If extensive repeated write commands are sent and commenting is desired for a group of bytes, the >
command can be used to extend the bytes to other lines that follow. A usage example for the > command
follows:
#example script for '>' command I i2cfast # Write AA and BB to registers 3 and 4, respectively w
30 03 AA BB # Write CC, DD, EE and FF to registers 5, 6, 7 and 8, respectively > CC DD EE FF #
Place a commented breakpoint b "AA BB CC DD EE FF was written, starting at register 3" # Read
back all six registers, starting at register 3 r 30 03 06
The following example demonstrates usage of the Wait for Flag command, f:
#example script for 'wait for flag' command I i2cfast # Switch to Page 44 w 30 00 2C # Switch
buffers w 30 01 05 # Wait for bit D0 to clear. 'x' denotes a don't care. f 30 01 xxxxxxx0

Writing Scripts
www.ti.com
Any text editor can be used to write these scripts; Jedit is an editor that is highly recommended for general
usage. For more information, go to: http://www.jedit.org.
Once the script is written, it can be used in the command window by running the program, and then
selecting Open Script File... from the File menu. Locate the script and open it. The script is then displayed
in the command buffer. The user can also edit the script once it is in the buffer and save it by selecting
Save Script File... from the File menu.
Once the script is in the command buffer, it can be executed by pressing the Execute Command Buffer
button. If there are breakpoints in the script, the script executes to that point, and the user is presented
with a dialog box with a button to press to continue executing the script. When ready to proceed, push that
button and the script continues.
