Hardware Overview www.ti.com
1 Hardware OverviewThe TAS5754/6MDCAEVM showcases the latest TI digital input class D closed loop amplifier. TheTAS5754/6M is an I2S or TDM input class D amplifier with PurePath HybridFlows. The EVM is used inconjunction with the PurePath Console Motherboard (PPCMB). The PVDD supply is provided via theTAS5754/6MDCAEVM and is regulated to 5 VDC and 3.3 VDC on the PPCMB. The PPCMB provides theI2S, I2C, and 3.3 VDC to the TAS5754/6MDCAEVM.
Figure 1. PPCMB and TAS5754/6MDCAEVM
1.1 TAS5754/6MDCAEVM Features• GUI control via USB port• Hardware programmable gains and switching frequencies• Stereo and mono channels with I2S input• Processed and non-processed mono channel I2S input• Operates in BTL or PBTL
1.2 TAS5754/6MDCAEVM Gain and FSWThe 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, and768 kHz. The combination of gain and FSW can be set by modifying the location of the shunt resistor onthe top side of the TAS5754/6MDCAEVM. The recommended default setting is 20 dB and 768 kHz. AFSW of 768 kHZ is recommended to minimize the ripple current in the 4.7-µH inductor used.

www.ti.com Hardware Overview
1.3 TAS5754/6MDCAEVM FunctionsThe TAS5754/6MDCAEVM is controlled by the PPCMB. The PPCMB sends I C commands from PPC tothe 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 USBaudio, optical SPDIF, coaxial SPDIF, and analog ADC sources. When a digital audio data input isselected, the PPC2 automatically sends appropriate scripts to the device in use.
1.4 TAS5754/6MDCAEVM Detailed OperationsUpon power-on, the PPCMB uses USB audio input (default). The I2S signals, LRCLK, SCLK, SDIN, andMCLK, come from the TAS1020B. foobar2000 or similar non-processing media source can be used tostream audio. The TAS1020B enumerates as the following device on a Microsoft® Windows® operatingsystem (OS): USB audio (USB-miniEVM), Human Interface Devices, and USB Composite Device, seeFigure 2.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current andcomplete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of salesupplied 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 termsand conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessaryto support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarilyperformed.TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products andapplications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provideadequate 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, orother intellectual property right relating to any combination, machine, or process in which TI components or services are used. Informationpublished by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty orendorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of thethird 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 alterationand is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altereddocumentation. 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 servicevoids 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 requirementsconcerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or supportthat may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards whichanticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might causeharm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the useof 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 tohelp enable customers to design and create their own end-product solutions that meet applicable functional safety standards andrequirements. 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 partieshave 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 inmilitary/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI componentswhich have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal andregulatory 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 ofnon-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
