1 Overview
The TAS5753MD evaluation module showcases the latest TI digital input Class-D open-loop amplifiers.
The TAS5753MD is an I²S input Class-D amplifier with audio processing features and integrated
headphone/line driver.
The EVM is configured in Two-Device 2.1 mode with one stereo device using bridge tied load for left and
right channels and one mono device configured for mono applications, such as higher power full-range
speakers or subwoofers. The device operating in stereo mode has the headphone/line driver option
available via a 3.5-mm plug connector. The EVM is used in conjunction with the PurePath Console
Motherboard (PPCMB). The PVDD supply is input on the EVM daughter card, which passes it to the
PPCMB motherboard through the J4 connector. Regulators on the PPCMB create the 3.3-V power supply,
which is sent back to the DUT through the J4 connector. The EVM is controlled by PPC3 software.

Multiband AGL and Full-Band AGL
The TAS5753MD features three multiband AGLs, as well as a full-band AGL. The multiband AGL is
used as a three-band crossover, having an independent custom configuration for low, high, and mid
frequency bands.
The multiband AGL and full-band AGL also offer the option to use preset configurations based on
output power, available for the use of standard power supplies and loads. These presets offer a good
starting point towards the full configuration of the end system.
Table 2. Available Presets for Multiband AGL
TAS5753MD Presets
15 W with 12-V PVDD, 4-Ωload
10 W with 12-V PVDD, 4-Ωload
20 W with 24-V PVDD, 8-Ωload
15 W with 24-V PVDD, 8-Ωload
15 W with 19.6-V PVDD, 6-Ωload
10 W with 19.6-V PVDD, 6-Ωload
The filters used for the multiband AGL crossover are configured according to the specific need. By
default, the three-band crossover frequencies are set to 300 Hz and 3 kHz, using second-order
Linkwitz-Riley filters. This filter type was chosen so the total sum of the three-band signals has a flat
response without having to calculate individual cross-over frequencies for unity summation. The
crossover frequencies were selected so they are separated far enough in the frequency range from
each other to avoid any dip caused by the filter sum response. For the mid-band mixer, the coefficients
range is different and features negative values. This is done because when using second order filters to
form a band-pass filter; the phase of the signal is inverted, causing an undesired frequency response
when summing all the signals. This phase inversion is corrected by using negative coefficients for the
mid-band mixer.

The AGL crossover configuration has two operating modes that can
be selected on the top of the main plot:
In basic mode, the crossover frequencies are ganged for left and
right channels, and the filters are configured so cutoff frequencies for
lowpass, bandpass, and highpass filter are matched.
In advanced mode, the user can modify these parameters
individually as well as have a different configuration for left and right
channels for the stereo device.
An Input/Output chart is available to easily configure the threshold
levels for each band. Drag and select each threshold and fine tune
the desired threshold level by controlling the levels in the lower part
of the window. Modify the Softening parameter to configure the
sharpness of the compression knee of the AGL.
Attack and release parameters are available for AGL tuning:
Attack Rate: This parameter sets the rate of the attack over the
output signal when it is greater than the desired threshold level. This
parameter acts fast enough to avoid apparent clipping before
engaging.
Release Rate: When the threshold is raised, this parameter reflects
the release rate of the compressed signal.

Dump Current State into a Header File
This feature allows generation of a configuration file for the evaluated device according to the features
evaluated and configured with PPC3. Different options are available for file generation, including the
format (.h, .cfg, .mtk), sample rate, device address, and so forth. The generated file is saved in the PC or
can be sent to the output window that appears in the window. Take into account that the register
configuration is generated from the device that is selected (Mono or Stereo).
Use the tuning snapshots feature to save several different operation modes for the device in the end-
system. In order to achieve this, first select the desired snapshot, then go to the End System Integration
window and generate the configuration file.
In-System Debugging
This tool helps debug the device when integrated in the end-system. This is possible by connecting the I²C
signals of the end-system device to the SCL, SDA, and GND test points of PPCMB. Limited features of
the TAS5753MD application are available in this mode. Disconnect from System Debug Mode by clicking
on the Disconnect button on the lower left corner of the window.
In-System Tuning
Once the device is integrated in the end application, make fine tuning adjustments to the audio processing
with In-System Tuning. As with In-System Debugging, this is done by connecting I²C signals from PPCMB
to the end-system amplifier. Audio processing features are available in this mode, allowing the option to
fine tune the AGL, equalizers, and mixing block in the end system.

4 Board Layout, Bill of Materials, and Schematic
This section includes recommendations, the EVM board layouts, bill of materials, and schematics.
The evaluation module has the stereo device populated in the upper section of the board, while the mono
device is located on the lower part of the board. A headphone connection is available on the top of the
board, it is connected to the output of the headphone/line driver integrated in the stereo device. The
connector for the power supply is located between both amplifiers. The connector that interconnects the
evaluation module with the PPCMB is located in the left side of the board on the bottom face. The EVM
features three connectors at the right side of the board used for the connection of the speakers and loads
that are used together with the EVM. These connectors correspond to left and right channel of the stereo
device and the single output of the mono device. The board has two standoffs located on each corner of
the right side, allowing structural stability when connected to the controller board.
Figure 9. TAS5753MDEVM
All the basic components required by the amplifier are located in the top of the board. The output filters
are located on the right side of each amplifier, keeping the distance between the inductor and capacitor as
short as possible. Each amplifier has a 0.1-µF decoupling capacitor populated close to the device as well
as bulk capacitors close to each PVDD pin connection. The design has wide open areas at the top and
bottom part of the amplifier to increase the thermal dissipation of the amplifier.

TAS5753MD Evaluation Module
The bottom layer of the board is designed to have a clear path that is used as a heat escape from the
device. RC-snubber circuits are not generally required in properly-designed 2-layer or 4-layer designs.
However, in systems where capacitors for PVDD or LC filter placement is compromised, the snubber
circuit is used to slow down the output square waves coming from the IC speaker outputs. A snubber
circuit for each output is featured in the evaluation module to showcase their recommended position, if
required for an end-system. The circuits are positioned so the thermal flow of the device has a radial clear
path out of the board.
Figure 11. Bottom Layer Thermal Flow
By default, the output filter of the stereo device is configured in BD mode. The user is able to evaluate the
devices in AD mode by populating the optional AD capacitors (C26, C29, and C65) in the evaluation
module. The I²C address of the devices can be changed as well, if required. By default, the stereo device
has an address of 0x56 and the mono device address is 0x54. Resistors R18, R19, R20 and R21
determine the address of each amplifier. Refer to the schematic of the evaluation module for more
information.
Figure 12. TAS5753MDEVM Optional Features
The evaluation module is a four-layer board designed to enhance the thermal performance and
robustness of the design. The second layer is used as ground plane, while the third layer contains the
power planes that distribute the supply voltages through the board.
TI recommends following the layout of this EVM as close as possible to get the same performance
obtained during the evaluation of the device. Any design variation can be supported by TI through
schematic and layout review, as in the case of a different layer number, filter option, and component
location, or if performance issues are present in the end-design. Join the audio amplifier discussion forum
at e2e.ti.com for additional design assistance.
