Introduction
The TLV320AIC36EVM is in the Texas Instruments (TI) modular EVM form factor, which allows direct
evaluation of the device performance and operating characteristics and eases software development and
system prototyping.
The TLV320AIC36EVM-K is a complete evaluation/demonstration kit, which includes a USB-based
motherboard called the USB-MODEVM Interface board and evaluation software for use with a personal
computer (PC) running the Microsoft Windows XP operating system.
The TLV320AIC36EVM-K is operational with one USB cable connection to a PC. The USB connection
provides power, control, and streaming audio data to the EVM for reduced setup and configuration. The
EVM also allows external control signals, audio data, and power for advanced operation, which allows
prototyping and connection to the rest of the development or system evaluation.

EVM Description and Basics
This section provides information on the analog input and output, digital control, power, and general
connection of the TLV320AIC36EVM-K.
2.1
TLV320AIC36EVM-K Block Diagram
The TLV320AIC36EVM-K consists of two separate circuit boards, the USB-MODEVM and the
TLV320AIC36EVM. 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 TLV320AIC36EVM 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 TLV320AIC36EVM 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 TLV320AIC36EVM is designed to fit over both of the smaller
evaluation module slots as shown in Figure 1

TLV320AIC36EVM-K Setup and Installation
www.ti.com
2.5.1
Stand-Alone Operation
When used as a stand-alone EVM, power is applied to P3/J3 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
TLV320AIC36 data sheet before applying power to the EVM.
P3/J3 provides connection to the common power bus for the TLV320AIC36EVM. Power is supplied on the
pins listed in Table 7.
The TLV320AIC36EVM-K motherboard (the USB-MODEVM Interface board) supplies power to J3 of the
TLV320AIC36EVM. 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 TLV320AIC36EVM is installed on the USB-MODEVM Interface board, aligning J1, J2,
J3, J4, and J5 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
TLV320AIC36EVM-K will enumerate as a "USB Human Interface Device" and as a "USB Audio
Device".
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 TLV320AIC36EVM-K software installation (described in Section 3.2) is complete, evaluation and
development with the TLV320AIC36 can begin.

AIC36 Control Software
The AIC36 Control Software (CS) is an intuitive, easy-to-use, powerful tool to learn, evaluate, and control
the TLV320AIC36. This tool was specifically designed to make learning the TLV320AIC36 easy. The
following sections describe the operation of this software.
NOTE: For configuration of the codec, the TLV320AIC36 block diagram located in the TLV320AIC36
data sheet is a good reference to help determine the signal routing.
4.1
Main Panel Window
The Main Panel window, shown in Figure 2, provides easy access to all the features of the AIC36 CS. The
Firmware Name and Version boxes provide information about the firmware loaded into the EVM's
EEPROM.
The USB Interface drop-down menu allows the user to select which communication protocol the
TAS1020B USB Controller uses to communicate with the TLV320AIC36 or to toggle the TAS1020B GPIO
pins. The USB-MODEVM Interface selection is global to all panels, including the Command-Line Interface.
The I2C Address box sets the global I2C address to be used by controls and indicators. Note that scripts
executed in the command line interface and in other panels use the I2C address provided in each
command and not the global I2C address.
The Panel Selection Tree provides access to typical configurations, features, and other panels that allow
the user to control the TLV320AIC36. The tree is divided into several categories which contain items that
pop up panels. A panel can be opened by double-clicking any item inside a category in the Panel
Selection Tree.
Below the Panel Selection Tree are three buttons that pop up the following:
•
•
•
Status Flags - Allows the user to monitor the TLV320AIC36 status flags.
Register Tables - A tool to monitor register pages.
Command-Line Interface - A tool to execute/generate scripts and monitor register activity.
The USB LED indicates if the EVM kit is recognized by the software and the ACTIVITY LED illuminates
every time a command request is sent.
The dialog box at the bottom of the Main Panel provides feedback of the current status of the software.
For USB-MODEVM firmware versions 2.01 and above, it is possible to update the firmware on-the-fly.
This is useful for cases in which different USB Audio sampling rates are desired, or when a new firmware
version is released. The "USB Audio Sampling Rate" dialog box displays the current USB audio sampling
rate supported by a particular firmware. Details on how to re-program the firmware are available in Section
4.1.4.

To use the default EVM settings with the Biquad Filter Tool click on the "Recording" application and
download for example the line-input script to setup EVM for line-in recording then proceed to use the
Biquad Filter Tool.
Step 1: Select the Processing Block - This specifies the number of biquads available (3 or 5) and stereo or
mono (right). For best results use Processing Block PRB_R2 as this works well with the default EVM
setup.

Step 2: Specify the Sample Rate - This is a key design parameter input to the Biquad Tool. The default is
44.1kHz which is the sample rate used on the EVM. The tool will work with any sample rate from 8kHz to
96kHz, however, if a sample rate other than 44.1kHz is selected then the user must go the the clock panel
to modify the PLL and/or clock settings so that the desired sample rate is setup properly when used with
an external audio interface.
Step 3: Specify the Biquad Filters - Select the filter type and subtype and enter any required parameters.
Note that the parameters not used will be grayed out. Use the "Plot" Check-Box to select the filters to plot
and/or download.
Step 4: Calculate the Coefficients - Click on the "Calculate Coefficients" OK button. This calculates all the
selected filters and plots the combined response of all the checked filters. If a filter is not checked it is
treated as an All-Pass filter.
Step 5: Inspect the Plots - Based on the selected filters determine if this is the total desired response.
Also, inspect the Scale (dB) display. Some filters may create a negative gain error which is reflected in the
scale. For example, if the Scale displays 0.5 there is a - 0.5dB gain error which can be corrected in the
analog PGA or the digital Volume. In the last column the stability of the filter is indicated. If the roots of the
filter denominator are less than 1 then the filter is stable and this field will display the text "Stable".
Otherwise, it will display the text "Unstable" meaning that the unstable filter should be re-specified until it is
stable.
Step 6: Download the Coefficients - Click on the "Download Coefficients" OK button. This action will
download the filter coefficients to the device. Note that in order to download coefficients into the device,
the following register writes are done:
1. Page 0 - Select processing block and Power-Down both ADCs
2. Page 4 - Write filter coefficients to both left and right channels as required
3. Page 0 - Power-Up both ADCs
Note that the filter coefficients can be saved as an I2C script by using the Command-Line Interface
Record Button. The I2C commands will be displayed in the Command Buffer which can be selected and
copied to a text command file.

To test the filters with USB Audio, select a configuration from the 'Typical Configurations>Playback' panel.
The 'Stereo DAC Playback' configuration is optimized for any 'Filter A' processing block. Alternatively, a
custom script can be loaded into the Command-Line Interface panel before downloading coefficients. This
tool assumes that Adaptive Filtering is enabled for real-time filtering.
Step 1: Select the Processing Block - This specifies the number of biquads available and stereo or mono
(left). For best results, use Processing Block PRB_P2 as this works well with the default EVM setup. To
change the processing block on the device:
1. Go to the 'Analog Settings>Audio Outputs' panel to uncheck the 'Enable DACs' box.
2. Go to the 'Signal Processing>Processing Blocks' panel to select the DAC processing block.
3. Go to the 'Analog Settings>Audio Outputs' panel to check the 'Enable DACs' box.

Automatic Gain Control
The left-channel Automatic Gain Control (AGC) can be enabled by checking the Enable Left AGC box
(Figure 12). 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 TLV320AIC36EVM-K
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.

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.

Command-Line Interface Panel
The Command-Line Interface panel provides a means to communicate with the TLV320AIC36 using a
simple scripting language (described in Section G.1). The TAS1020B USB Controller (located on the USBMODEVM motherboard) handles all communication between the PC and the TLV320AIC36.
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 21).
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.1 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.
The Record button generates script commands based on data written by other panels.

Appendix G USB-MODEVM Protocol
G.1
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
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.
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).
Following these two bytes are data, if writing; if reading, the third byte value is the number of bytes to
read, (expressed in hexadecimal).

Writing Scripts
www.ti.com
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 8 w 30 00 08 # Switch
buffers w 30 01 05 # Wait for bit D0 to clear. 'x' denotes a don't care. f 30 01 xxxxxxx0
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.
