TAS5755MEVM Evaluation Module
2.1.2 PSU Interface
The TAS5755MEVM is powered by two power supplies: a 5-V power supply (VIN) connected to the
MC57xx controller board, and the PVDD power supply connected directly to the EVM board. The 3.3-V
level is generated on the controller board by a voltage regulator from the 5-V supply.
NOTE: The power-supply cable length must be minimized. Increasing the length of the PSU cable
increases the distortion of the amplifier at high output levels and low frequencies.
The maximum output-stage supply voltage depends on the speaker load resistance. Check the
recommended maximum supply voltage in the TAS5755 data sheet (SLOS982).
2.1.3 Loudspeaker Connectors
CAUTION
All speaker outputs are biased at VCC / 2 and must not be connected to ground
(for example, through an oscilloscope ground).
Loudspeaker connections vary by device setup and the evaluation module features a dedicated connector
for each configuration. When using SE or BTL mode, ensure that the jumper J9 is populated indicating
that BTL rather than PBTL mode is enabled. When connecting a speaker in SE mode, connect the
TAS5755MEVM speaker to one of the two SE connectors labeled SE A (J2) and SE B (J4). When
connecting a speaker in BTL mode, connect the speaker to one of the two BLT connectors labeled BTL
AB (J3) and BTL CD (J6). Note that the EVM is set up to use only channels A and B in the SE mode, for a
production application; however, any of the four channels (A, B, C, D) can be setup for SE mode
operation. To use PBTL mode, depopulate the jumper on the header labeled J9 and populate jumpers J10
and J11 with a high-current wire or jumper. The speaker can then be connected to the connector labeled
PBTL (J5).
Speakers or loads can be connected to the outputs A-D with clip leads, or cables can be made
with female connectors (JST VHR-2N) that can mate to male connectors on the EVM board.

2.1.4 USB Interface
The TAS5755M registers are accessed through I2C bus lines SDA and SCL. The USB circuit and USB
connector on the MC57xxPSIA board facilitates the connection between a host computer and the device.
The EVM USB circuit is powered by the 5-V USB line of the host PC and is independent of the power
supplies available on the board. The USB device that is used is a TAS1020B from Texas Instruments.
2.1.5 Digital Audio Interface SPDIF
The Digital Audio Interface SPDIF (RCA, OPTO) accepts digital audio data using the I2S protocol. See the
TAS5755M data sheet for more information.
The RCA connector and the OPTO connector are the two SPDIF interfaces on the MC57xxPSIA board.
The jumper JP11 toggles between the OPTO and RCA connector to accommodate the signal source.
When the RCA cable or optical cable is connected and the signal source is powered up, verify that the
SPDIF lock indicator (blue LED5) illuminates, confirming that a viable signal is available to the device.
Install a jumper on JP4 across the middle pin and the pin marked SPDIF to connect the digital source to
SDIN1. Install a jumper on JP5 to connect the digital source to SDIN2.
For detailed information on how the data and clocks are provided to the TAS5755M, see Figure 24 and
the DIR9001 device data sheet (SLES198).
2.1.6 ADC Interface
In the absence of a digital signal source, the PCM1808 ADC can be used to convert an analog audio
signal to a digital signal to the TAS5755M. The DIR9001 still provides clock signals to the ADC in this
process. A 12-MHz crystal is installed on the MC57xxPSIA board. The ADC is an additional feature of this
board to provide flexibility in sourcing an audio signal to the TAS5755M. Review the PCM1808 data sheet
(SLES177) for a detailed description of the ADC on this EVM. Install the jumper on JP4 and J5 across the
middle pin and the pin marked ADC to select ADC as the source for SDIN1 and SDIN2, and finally, install
JP2 and JP3.
2.1.7 Board Power-Up General Guidelines
Connect the MC57xxPSIA and the TAS5755MEVM boards by locating pin 1 on each board, indicated by a
small white triangle. The MC57xxPSIA plugs down onto the TAS5755MEVM board (that is, the
TAS5755MEVM board fits underneath the MC57xxPSIA board). Pin 1 on each board must be connected
to each other.
Install the EVM software on the PC before powering up the board. After connecting the loudspeakers or
other loads, power supplies, and the data line, power up the 5-V power supply first; then power up the
PVDD power supply.
2.2 Software Installation
Download the TAS57X1 Graphical Design Environment (GDE) from the TI Web site, located on the
TAS5755MEVM product page. The TI Web site always has the latest release and any updates to versions
of the GUI.
NOTE: The TAS5755MEVM is recognized as a TAS5731 device by the GDE software. The
TAS5731 device must be selected in the software when using this EVM.
Execute the GUI install program, Setup.exe. Once the program is installed, the program group and
shortcut icon is created in Start →Program →Texas Instruments Inc →TAS57X1 GDE.
The TAS5731 tab opens when the GUI starts. The TAS5731 tab has two subwindows. One shows the
Process Flow window. This window also shows Input select, Mode select, Channel, and Master Volume.
All functions are shown in the same order as in the device.
The other subwindow, the Properties window, has the properties that a user can update by selecting from
the available options. The properties available depend on the device selected.

3.2 Setting the I2C Device Address
The I2C slave address of the TAS5755 can either be 0x34 or 0x36 depending on the state of Pin 21
(Addr/Fault) at device power on. The slave address is 0x34 when Addr/Fault is low and 0x36 when it is
high. By default, the EVM address is configured to 0x34 with Addr/Fault pulled low by R12. The slave
address can be set through the GUI by navigating to the Tools menu and opening the I2C Memory Tool.
Clicking the Change Device Address button opens a dialog to specify the device address as shown in
Figure 9. By default the EVM device address is 34 so the address should be changed by entering 34 and
clicking change.

3.3 Initializing the Device
Figure 10 shows a snap-shot of the GUI when it is first launched. The different blocks seen on the GUI
window are defined functions that can each be used to set the register space to a desired value. (For
example, the volume block shown in Green, can be used to set the desired master-volume level. Changes
made to this block, update the master-volume register with the corresponding hex value).
Figure 10. Default GUI Interface on Start-up
The drop-down properties menu seen on the right-hand side of the GUI window (Figure 10) is used to
specify the device to be used. A zoomed snap-shot of the properties menu is shown in Figure 11. Select
TAS5731 from the CurrentDevice option menu. Other settings like modulation scheme (AD or BD),
operation mode (2.0 or 2.1), and so forth, can also be specified using this menu.

To initiate the GUI control, the first step is to ‘Connect’ the GUI. To do this, scroll to the Target section of
the menu and click on Connect (as shown in Figure 12)
Figure 12. Initiating Connect from the Target Menu
After the Target-Connect operation, the GUI window background changes from white (with grid) to a solid
light-green. All the blocks seen in the GUI window are now active and any updates made on these blocks
updates the corresponding register space. Also, note that the configuration menu options on the right-
hand side (highlighted with blue-box in Figure 13) are now grayed out and cannot be updated. The Target-
Connect operation automatically updates the trim register (0x1B) to factory-trim mode, now the device can
be set to stream audio output with only two additional operations: exit-shutdown and un-mute
The device shut-down mode can be toggled through the Shutdown checkbox (highlighted with a red-box in
Figure 13). Uncheck this box to bring the device out of shutdown. Similarly, the mute state of master
volume can be toggled using the Mute checkbox (highlighted with a red-box in Figure 13). After un-muting
the master volume, use the volume slider to set the volume to the desired level. The current volume level
is displayed in the menu area on the right-hand side of the GUI window. After completing these basic
operations, the device can now stream audio.

3.4 Using EQ Function
The Bi-Quad registers in the TAS5755M can be programmed for EQ and other signal processing
applications using the BQ blocks on the GUI. Commonly used signal processing functions are EQ, Treble-
Shelf, Bass-Shelf, Low-pass, and high-pass filters. In particular, the EQ function can be used to equalize
(hence the name EQ) the non-ideal frequency response of the speaker. The BQ blocks on the GUI are
highlighted in Figure 14.
Figure 14. TAS57xx GUI EQ Blocks
When a BQ-block is selected on the GUI by using a single mouse click, the device registers associated
with that particular BQ block are displayed in the properties window. Double-Clicking on the BQ-block,
opens the Filter Creation Tool for TAS570x window. The Figure 15 shows the filter-creation window
corresponding to block BQ1, where eight bi-quad registers are available for programming. Each of these
can be independently programmed by using the corresponding entry fields. The default setting for all bi-
quads is AllPass mode. The different filter options available are seen in the drop-down menu in Figure 15.
The frequency and phase response of the filters can be viewed using the frequency and phase response
tabs of the filter tool. Finally, when the Apply button is clicked, the bi-quad registers of the device are
updated with the programmed settings.

3.4.1 Woofer Channel Defaults to Low Pass Configuration
The GUI defaults to a 2.1 configuration where the BTL CD channel receives a low pass filter. However,
due to a bug in the GUI, this low pass filter is not shown. To fix this problem the BQ4a block should be
opened and the current settings applied to the channel by clicking the Apply button as shown in Figure 16.
This will ensure the GUI and the EVM filters are in sync.
Figure 16. Fixing Low Pass Filter Bug on Woofer Channel
3.5 Using the DRC Function:
The TAS5755M has two DRC blocks; DRC-1 and DRC-2. Left and right channels are processed using
DRC-1, and the sub-channel is processed via DRC-2. The DRC blocks on the TAS57X1 GUI are
highlighted in Figure 17. A single click on the DRC block brings up the I2C register information in the
properties window as seen in Figure 17. The default state of the DRC control is in disabled state, as seen
in the Runtime Properties section of Figure 17. To use the DRC function in the GUI, update the DRC
control to the Enabled state. Note that the DRC-1 and DRC-2 have independent enable and disable
controls.

3.6 Using the Mixer and Scaler Nodes
Figure 20 shows a snap shot of the different mixer and scaler blocks from the GUI. The mixer nodes can
be used to mix the contents of the different channels. The input mixer can be used to mix the channels
before they are processed by the bi-quads and DRC, while the output mixer nodes are used to mix the
channels after they are processed through these blocks. The scaler blocks at the output can be used to
scale the outputs.
Clicking on any of these blocks displays their configuration options in the properties window. Figure 20
shows an example where the output-mixer 0x51 is selected. Update the mixer configuration by changing
the values in the properties window.

3.7 Using the I2C Memory Tool
The GUI installation includes an I2C read-write interface, called the Memory Tool. Using the Memory Tool,
the device registers can manually be read or written to. The tool can either be opened using the GUI
menu (as shown in Figure 21), or can also be launched stand-alone even when the GUI window is not
opened, through the Windows →All-Programs →Texas Instruments Inc →I2C Memory tool option. The
stand-alone capability is especially convenient when an existing I2C file needs to be loaded to update
device registers or when performing I2C debug.
Figure 21 shows a snap-shot of the Memory Tool window. Click the I2Ctab at the top to view the
Read/Write and Execute I2C Command File options. For Read operation, provide register sub-address
and register size (length) in bytes. Clicking on the Read button displays the contents of the register in the
Data window. For a Write operation, provide the data to be written in the Data field, and then click the
Write button.
The Memory Tool can also be used to load a pre-defined I2C register file. Clicking the browse button on
the bottom-right allows the user to browse to the location of the I2C script file, after selecting the desired
file, clicking the Execute button, implements the register write operations specified in the file.
