Hardware Overview
The TAS5754/6MDCAEVM showcases the latest TI digital input class D closed loop amplifier. The
TAS5754/6M is an I2S or TDM input class D amplifier with PurePath HybridFlows. The EVM is used in
conjunction with the PurePath Console Motherboard (PPCMB). The PVDD supply is provided via the
TAS5754/6MDCAEVM and is regulated to 5 VDC and 3.3 VDC on the PPCMB. The PPCMB provides the
I2S, I2C, and 3.3 VDC to the TAS5754/6MDCAEVM.

TAS5754/6MDCAEVM Gain and FSW
The TAS5754/6MDCAEVM offers hardware programmable gains and PWM switching frequencies (FSW).
The two gain options are 14 dB and 20 dB. The four FSW options are 384 kHz, 480 kHz, 576 kHz, and
768 kHz. The combination of gain and FSW can be set by modifying the location of the shunt resistor on
the top side of the TAS5754/6MDCAEVM. The recommended default setting is 20 dB and 768 kHz. A
FSW of 768 kHZ is recommended to minimize the ripple current in the 4.7-µH inductor used.

1.3
TAS5754/6MDCAEVM Functions
The TAS5754/6MDCAEVM is controlled by the PPCMB. The PPCMB sends I C commands from PPC to
the TAS5754/6M. Upon PPC2 execution and connection, the TAS5754/6M is put in software mode.
The digital audio data input to the TAS5754/6MDCAEVM is sent from PPCMB and is selectable from USB
audio, optical SPDIF, coaxial SPDIF, and analog ADC sources. When a digital audio data input is
selected, the PPC2 automatically sends appropriate scripts to the device in use.
1.4
TAS5754/6MDCAEVM Detailed Operations
Upon power-on, the PPCMB uses USB audio input (default). The I2S signals, LRCLK, SCLK, SDIN, and
MCLK, come from the TAS1020B. foobar2000 or similar non-processing media source can be used to
stream audio. The TAS1020B enumerates as the following device on a Microsoft® Windows® operating
system (OS): USB audio (USB-miniEVM), Human Interface Devices, and USB Composite Device, see
Figure 2.

TAS5754/6MDCAEVM Setup
This section describes the TAS5754/6MDCAEVM setup and software installation. Since PPCMB connects
to one of the device under test (DUT) EVMs, it is necessary to show the connection in this section.
TAS5754/6MDCAEVM is used for this purpose.

Figure 4. Manual Target Detected
The PPC2 software starts up in Basic mode as shown in Figure 5.The green LED on the bottom left
corner of the PPC2 Window indicates the initialization of TAS5754/6M is valid. The PPCMB is initialized
with the USB audio (USB-miniEVM) selected. Streaming audio from the USB host is routed to the
TAS5754/6M.
Figure 5. TAS5754/6MDCAEVM GUI Initialization
If an optical input is used, simply select Optical from the PPCMB Audio I/O drop-down menu in the PPC2
software, the I2S is then routed with this signal, likewise, when a coax input is selected using the PPCMB
Audio I/O drop-down menu. If an analog input is used, click on Line1 from the PPCMB Audio I/O dropdown menu in the PPC2 software, the ADC (PCM3168A) is the source of I2S data.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
