Hello, everyone. Today, we are going to walk you through the unboxing and setup of the evaluation module, also referred to as an EVM, for the TAS6511-Q1 amplifier. The EVM package includes the EVM PCB and a disclaimer. You will need a micro USB cable, speaker and power cables, a speaker or a resistor load, and access to the TAS6511-Q1 Pure Path Console 3 software for the EVM.
Shown here is a list of hardware and software needed to set up the EVM. For further details on hardware and software setup, PCB schematic, bill of materials, and layout, please refer to the EVM user's guide on www.ti.com.
Now we will unbox the TAS6511-Q1EVM and show you how to configure it. After removing the EVM from the box, connect the micro USB cable from the PC to the EVM. Connect the speaker to J6 and J7, and then connect the power supply to PVDD.
Set the switch S1 button as needed. Typically, S1 is down. S1 is up for coaxial input, and S1 is down for optical input.
Set the switch S3 as needed. S3 is in the up position for power down and in the down position for normal operation. Then connect your audio source. This can be a DVD player or audio test equipment with optical or coaxial SPDIF output or a media player from the PC.
The digital audio input can be provided through the USB, the optical input, the coaxial input, or directly through the I2S or TDM headers. Turn on the PVDD power supply and launch the TAS6511-Q1EVM PPC3 plugin on the PC.
For the next part of this demo, you will need to have Pure Path Console 3, or PPC3, downloaded and installed. For instructions on accessing and installing this software, please refer to the TAS6511-Q1EVM user's guide.
After completing these steps, start up the PPC3 app and go to the TAS6511 home window. You should see the following icons-- Device Monitor & Control, Register Map, Audio Processing, and an I2C button on the bottom of the window. Click the Connect button if not already connected, and you will be able to communicate to the device.
The Device Monitor & Control window has five major sections-- Channel Control box, Miscellaneous Control box, Faults/Warnings box, AC Load Diagnostics box, and the DC Load Diagnostics box.
In the Channel Control box, change the channel mode from Hi-Z to Play using the dropdown menu. The audio input should play through the speaker output. The Audio Processing Options box allows you to control the DSP processing features that are available for the TAS6511-Q1. You can click the on/off slider to enable or disable a process, and some boxes can be opened to modify the process.
The PPC3 software allows you to easily view and modify specific registered values of the TAS6511-Q1 via the Register Map box in the home menu. The register map can be sorted alphabetically or by register number. When a register is selected, it is highlighted, and the field box to the right is populated with the register name, field descriptions, and current value for each field.
A bit changes state when double-clicked, and the state change is sent to the EVM at the end of the second click. You can change whole field values by double-clicking on the value in the field box, then entering the hex value you want to change to, pressing Enter to confirm the change. This can also be done with the Value box in the register map to change the whole register value at once.
The PPC3 GUI also has a window to use I2C directly with the TAS6511-Q1. Click on the I2C icon at the bottom of the PPC3 window, and the following window should be displayed. This window is used to help finalize and debug the end system design. You can use this tool to create the end system I2C code by using Log option or run debug scripts of the end system using I/O option.
