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 TAS5751M Presets 15 W with 12-V PVDD, 4-Ω load 10 W with 12-V PVDD, 4-Ω load 20 W with 24-V PVDD, 8-Ω load 15 W with 24-V PVDD, 8-Ω load 15 W with 19.6-V PVDD, 6-Ω load 10 W with 19.6-V PVDD, 6-Ω load 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. Figure 7. Multiband AGL – Three-Band Crossover SLOU440 – March 2016 Submit Documentation Feedback TAS5751M Evaluation Module Copyright © 2016, Texas Instruments Incorporated 9 Using the TAS5751MEVM with PurePath Console 3 www.ti.com 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. 10 TAS5751M Evaluation Module SLOU440 – March 2016 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated www.ti.com Using the TAS5751MEVM with PurePath Console 3 All the multiband AGL functions are also featured in the full-band AGL window. By default, –1 dB is configured for full-band AGL and the attack and release rates are set to 10 V/ms. Figure 8. Full-Band AGL 3.6 Register Map This window is used to monitor and change the main registers of the amplifier. The readings appearing on the registers are related to the selected device, that is, stereo or mono. Manual changes to the register values is accomplished by double-clicking in the desired bit to change. Clicking on Read All Registers allows monitoring of the register status of the amplifier. The Fields section shows the register name and a brief description of each bit that affects the selected register. 3.7 Direct I²C This tool manually reads and writes the registers of the amplifier. The Direct I2C window is also used to monitor the changes made to the device registers using a logging functionality. The stereo device I²C address of the EVM is 0x56, the mono device I²C address is 0x54. Direct I2C has two main tabs, I/O and Log, present in the top right corner of the window.

The End System Integration window has three main options for the customer (1) Dump Current State into a Header file, (2) In-System Debugging, and (3) In-System Tuning. 12 TAS5751M Evaluation Module SLOU440 – March 2016 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Using the TAS5751MEVM with PurePath Console 3 www.ti.com 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 endsystem. 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 TAS5751M 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.

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. 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. TAS5751MEVM 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. Figure 10. TAS5751M Layout 14 TAS5751M Evaluation Module SLOU440 – March 2016 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated www.ti.com Board Layout, Bill of Materials, and Schematic 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 (C24, C27, and C51) 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 R13, R14, R15, and R16 determine the address of each amplifier. Refer to the schematic of the evaluation module for more information. Figure 12. TAS5751MEVM 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.

FCC Interference Statement for Class A EVM devices NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. SPACER SPACER SPACER SPACER SPACER SPACER SPACER SPACER FCC Interference Statement for Class B EVM devices NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • • • • Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. 3.2 Canada 3.2.1 For EVMs issued with an Industry Canada Certificate of Conformance to RSS-210 Concerning EVMs Including Radio Transmitters: This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Concernant les EVMs avec appareils radio: Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Concerning EVMs Including Detachable Antennas: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. Concernant les EVMs avec antennes détachables Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le manuel d’usage et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne.
