3.5Operational Sequence and Indicators

After connecting the power supply and turning it on, the power supply current must be ~50 mA. The amplifier reset LED must be on.

The PVDD and 3.3-V LEDs must be on. If not, check the connections to the power supply.

Connect the SPDIF cable, either optical or coaxial, to an SPDIF source.

Connect the USB cable and the USB LED (blue LED must be on).

The EVM must enumerate without the installation of a USB driver; it is a Windows™ audio class device.

Start the GUI. (It must not give an indication of COMMUNICATION ERROR).

C:\Program Files\Texas Instruments Inc\TAS5086 GUI

Load the configuration file.

(File, Load, Config File, TAS5102 EVM Configuration.cfg)

The AMP RESET LED must go off.

The power supply current must be ~100 mA.

This indicates that the amplifier is switching and ready for audio input.

The SPDIF indicator must be on (blue LED), when locked to a valid source of SPDIF.

If the preceding conditions are met, the EVM system is ready to accept audio data.

Note: The default gain setting of the TAS5086 GUI is 0 dB. If you are connecting directly from a music source (CD player) for input and speakers for output, you may want to use the volume control function of GUI to reduce the gain before the program material is started.

4System Interfaces

This section describes the TAS5102/3 EVM board in regards to power supplies and system interfaces.

4.1Power Supply (PSU) Interface (PVDD and GND)

The TAS5102/3 EVM module must be powered from a well-regulated external power supply. Good audio performance requires a stabilized power supply with low ripple voltage and low output impedance.

Note: The length of power supply cable must be minimized. Increasing the length of the PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies.

Maximum output stage supply voltage depends of the speaker load resistance. For the recommended maximum supply voltage, see the TAS5102/3 data sheet (SLLS801).
