Complete System and EVM Signal Path Overview 2 Installation This section describes the EVM power supplies, system interfaces, and software installation. It provides information regarding handling and unpacking, absolute operating conditions, and switch and jumper positions. It also provides a step-by-step guide to setting up the EVM for device evaluation. 2.1 EVM Installation The following are the basic tools needed for the initial EVM power up. • Power Supply Unit (PSU) for Digital Supply (12 V) • PSU for PVDD (4.5 V to 26 V) • Banana-style test leads for power supplies • Optical or coaxial cable for SPDIF interface based on signal source • USB cable • EVM Software • Speaker or loads for outputs The following sections describe the EVM board in regards to power supplies (PSU) and system interfaces. 2.1.1 Connecting the EVM to the Input-USB Board3 On the right side of the Input-USB Board3 is a terminal block and another is located on the left of the EVM (labeled J1). Carefully place the Input-USB Board3 block above the EVM block and gently push down. 2.1.2 Power Supply Interface The EVM is powered by two PSUs connected to the Input-USB Board3 controller board: a 12-V PSU (VIN), and a 4.5- to 26-V PVDD PSU. The 3.3- and 5.0-V levels are generated on the board by voltage regulators from the 12-V supply. SLOU346 – July 2012 TAS5721-TAS5723EVM Evaluation Module Copyright © 2012, Texas Instruments Incorporated 3 Installation www.ti.com NOTE: Minimize the length of the PSU cable. Increasing the length of the PSU cable increases the distortion of the amplifier at high output levels and low frequencies. 2.1.3 Loudspeaker Connectors CAUTION All BTL speaker outputs are biased at Vcc/2 and must not be connected to ground (e.g., through an oscilloscope ground). 2.1.3.1 BTL Mode (2.0) When connecting a speaker in BTL mode, connect one speaker across the connector labeled LEFT and the other speaker to the connector labeled RIGHT. Figure 2. BTL Configuration 4 TAS5721-TAS5723EVM Evaluation Module Copyright © 2012, Texas Instruments Incorporated SLOU346 – July 2012 Installation www.ti.com 2.1.3.2 SE Mode (2.1) When connecting speakers in single-ended mode, connect one speaker across the connector labeled SEA and the other speaker to the connector labeled SE-B. To run in 2.1 mode, also connect a BTL speaker across the RIGHT connector (outputs C and D). Figure 3. SE/2.1 Mode Configuration 2.1.3.3 PBTL Mode When connecting speakers in a PBTL configuration, short OUT_A and OUT_B after the filter (so short the two pins of the connector labeled LEFT. Also short OUT_C and OUT_D after the filter (short the two pins of the connector labeled RIGHT. Connect one end of the speaker to OUT_A/OUT_B and the other end of the speaker to OUT_C/OUT_D Figure 4. PBTL Configuration 2.1.4 Headphone/Line-Driver The TAS5721 has a stereo output which can be used as a headphone amplifier or line driver that can output 2-VRMS. The headphone amplifier/line-driver on the EVM is configured for unity gain, adjusted by modifying R1, R2, R4, and R5. Gain = R2/R1 = R5/R4 SLOU346 – July 2012 TAS5721-TAS5723EVM Evaluation Module Copyright © 2012, Texas Instruments Incorporated 5 Installation www.ti.com The analog input goes into the HP-IN headphone jack. Plug the headphones or line-driver load into the HP-OUT headphone jack. Use a PWM input signal by installing C2, C3, C5, and C6 onto the EVM. Pressing the HP-SD button on the EVM shuts down the headphone amplifier/line-driver. 2.1.5 USB Interface The TAS5721 and TAS5723 device registers are accessed through I2C bus lines SDA and SCL. The USB circuit and USB connector on the Input-USB Board3 board facilitate 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 PSU available on the board. The USB device is a TAS1020B from Texas Instruments. The USB input streams audio. Toggling switch S7 to USB selects the USB I2S source over the SPDIF source. 2.1.6 Digital Audio Interface SPDIF The Digital Audio Interface SPDIF (RCA/OPTO) accepts digital audio data using the I2S protocol. See the TAS5721 or TAS5723 data sheet for more information. The RCA connector and the OPTO connector are the two SPDIF interfaces on the Input-USB Board3. The switch, S2, toggles between the OPTO and RCA connector (RCA connector labeled as COAX) accommodating 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 LED illuminates, confirming that a viable signal is available to the device. Use switch S7 to connect the SPDIF to the digital source SDIN1. 2.1.7 ADC Interface The PCM1808 ADC is used to convert an analog audio signal to a digital signal for the TAS5721 or TAS5723. The DIR9001 still provides clock signals to the ADC in this process. A 12.288-MHz crystal is installed on the Input-USB Board3. The ADC is an additional feature of this board providing flexibility in sourcing an audio signal to the TAS5721 or TAS5723. Review the PCM1808 data sheet (SLES177) for a detailed description of the ADC on this EVM. The PCM1808 only accepts up to a 1-VRMS input signal. Uninstalling jumpers JP300 and JP301 implements a voltage divider that halves the incoming voltage, allowing input of up to a 2-VRMS signal through the ADC1-IN audio jack. The EVM uses only one analog input jack, the ADC1-IN. If an analog input is connected, it takes precedence over any digital audio signal. 2.1.8 General Guidelines for Powering-Up the Board Connect the Input-USB Board3 and the EVM boards by locating pin 1 on each board, indicated by a small white triangle. The Input-USB Board3 plugs down onto the EVM board (the TAS5721-TAS5727EVM board fits underneath the Input-USB Board3). 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, PSU, and the data line, power up the PVDD power supply first; then power up the 12-V VIN power supply. 2.2 Software Installation Download the TAS57XX Control Console GDE from the TI Web site, located on the TAS5721TAS5727EVM product page. The TI Web site always has the latest release and any updates to versions of the GUI. 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 → ControlConsole. 6 TAS5721-TAS5723EVM Evaluation Module Copyright © 2012, Texas Instruments Incorporated SLOU346 – July 2012 Using the GUI www.ti.com 3 Using the GUI This section describes the details of using the TAS57xx ControlConsole Graphical User Interface (GUI) software tool to interface with the TAS5721 or TAS5723 device. The software is available for download at the EVM product page on www.TI.com. The GUI's main function provides an easy way to manipulate the device register space for attaining the required signal processing flow. Clicking the question mark in the upper right-hand corner of the GUI opens an introductory help file explaining each tab of the GUI. Read the help file for a complete understanding of the full functionality of the GUI. 3.1 ControlConsole Quick start 3.1.1 Launching ControlConsole Before opening ControlConsole, power the TAS5721-TAS5723EVM and Input-USB Board3, and connect the USB cord from the Input-USB Board3 to the computer. When starting ControlConsole an initialization script runs, turning on the device. If power to the EVM is lost, close ControlConsole and restart it, running the script again. Alternatively, enter the register values manually using the Direct I2C Access tab. Select the correct target when opening ControlConsole with the following steps: • Navigate to the Texas Instruments Inc title in the start program menu • Open the ControlConsole folder • Select the correct target, opening ControlConsole Double check the names of the tabs at the top of the GUI; the device name should be either TSA5721 or TAS5723 (depending on the IC used). A green circle appears in the lower left-hand corner of the GUI indicating that communication is established with the board. 3.1.2 Process Flow Tab The Process Flow tab options with their descriptions are shown in Table 1. Select the correct sample rate from the drop-down box in the lower left-hand corner of the GUI. While the TAS5721 and TAS5723 autodetect the sample rate, the GUI has no way of detecting what the sample rate is. Make sure the Mode setting in the lower right-hand corner of the GUI is correct. The TAS5721 and TAS5723 operate in 2.0 or 2.1 modes, depending on the desired speaker configuration. There is not a quick PBTL set-up option. Section 4 explains the PBTL set up. When finished setting-up, make sure the device is out of shutdown. In the lower right-hand corner of the Process Flow tab, the Shutdown button reads Exit if it is out of shutdown, and Enter if it is in shutdown. Click to toggle between the two. At this point, the device should stream audio. Use the Direct I2C Access tab for writing directly to the TAS572X registers. Use the TAS5723 Registers tab for viewing the current register values, as well as for modifications of individual bits. 3.1.3 1. 2. 3. 4. 5. 6. 7. Summary of Steps Power the TAS5721-TAS5723EVM and Input-USB Board3 Connect the Input-USB Board3 to the computer with a USB cable Open ControlConsole GUI with the correct target: (a) Verify that the GUI displays the correct device name (b) Verify that a green dot is displayed in the lower left-hand corner of the screen.
