SAP clock for master mode operation. 2.4.2 Configuring the EVM After completing the software installation, connect the USB cable to J7 on the TAS3208EVM-LC board. This connection powers the EVM and automatically enumerates the TUSB3210 USB Serial Controller required for communication between the host PC and the TAS3208 Digital Audio Processor. -
Page 14: Master/Slave Mode Operation
C clocks are still internally derived from the external crystal. Serial Digital Audio is input in to the TAS3208EVM-LC via the Serial Digital Input header (J1). Analog signals are input via the analog input header (J4), or the line in jack (J2). -
Page 15: Running The Process Flow
The GDE generates and assembles the code for the process flow, downloads it to the EVM, then resets the TAS3208EVM-LC board. At this point the GDE switches from Edit Mode to Run Mode, and streams audio from input to output. - Page 16 Quick Setup Guide SLEU097 – April 2008 Submit Documentation Feedback...
