    Chapter 1 SLEU093 – March 2008 Overview The TAS3308EVM PurePath Digital™ customer evaluation module demonstrates the Digital Audio Processor TAS3308 from Texas Instruments (TI). TAS3308 is a fully programmable high-performance audio processor. It uses an efficient, custom, multi-instruction programming environment optimized for digital audio processing algorithms. The TAS3308 architecture provides high-quality audio processing by using a 48-bit data path, 28-bit filter coefficients, and a single-cycle 28 ×...

The chapter provides information regarding handling and unpacking, absolute operating conditions, and a description of the factory default jumper configuration.
  • Page 14: Electrostatic Discharge Warning

    Power Supply Setup The TAS3308EVM is powered via the ±9 V terminals or the 9 V (center hot) power connectors, PJ1 and PJ2. The TAS3308 EVM generates a 5-V, –5-V, and 3.3-V internal supplies that are fed to the TAS3308EVM components.

    The TAS3308 has an optical SPDIF input from OPTO2. This is a pass though only connection to the TAS3308 SDOUT2/SPDIF output on, OPTO3. Master/Slave Mode Operation The TAS3308EVM is delivered configured to operate in clock master mode. However, the TAS3308 can be configured as a clock slave or master using JP3. Table 2-2. JP2 Clock Master/Slave Setting...

    Using the TAS3308 EVM After completing the software installation, turn on power supplies and connect USB cable to Input-USB board. To start the GDE – Go to the Start menu and select All Programs/Texas Instruments/PurePath Studio/PurePath Studio GDE. Quick Setup Guide SLEU093 –...
  • Page 17: Gde Startup

    www.ti.com TAS3308 Software Installation Figure 2-1. GDE Startup The startup of GDE takes few seconds. The TAS3308 requires an initialization configuration file to be loaded after a reset. This file configures the TAS3308 for the EVM configuration, enables the analog outputs, and sets the clock master/slave mode. Before loading or building a process flow verify that an initialization file is specified in the Execute I command file window.
  • Page 18: Specifying The I 2 C Initialization Sequence

    www.ti.com TAS3308 Software Installation Figure 2-3. Specifying the I C Initialization Sequence Then verify that the “Execute on reset” box is checked. At this point a process flow can be built using the TAS3308 application framework, the TAS3308 I/O components and the audio processing components. Building and running a process flow A good starting point is to load the predefined TAS3308 Test process flow.

  • Page 21: Gde Test Process Flow

    To build this process flow and execute it on the EVM, select Build/ Generate Code, then Build/Download code, and finally then Build/Run. When the GDE transitions to run mode, the GDE resets the TAS3308EVM. The reset restores the TAS3308 register to the default values.
