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.

Figure 2. Device Manager

2 TAS5754/6MDCAEVM SetupThis section describes the TAS5754/6MDCAEVM setup and software installation. Since PPCMB connectsto 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 leftcorner of the PPC2 Window indicates the initialization of TAS5754/6M is valid. The PPCMB is initializedwith the USB audio (USB-miniEVM) selected. Streaming audio from the USB host is routed to theTAS5754/6M.

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 PPC2software, the I2S is then routed with this signal, likewise, when a coax input is selected using the PPCMBAudio I/O drop-down menu. If an analog input is used, click on Line1 from the PPCMB Audio I/O drop-down menu in the PPC2 software, the ADC (PCM3168A) is the source of I2S data.
