  • Page 1: Table Of Contents

    Guide This user's guide describes the characteristics, operation, and use of the TLV320AIC33EVM, both by itself and as part of the TLV320AIC33EVM-PDK. This evaluation module (EVM) is a complete stereo audio codec with several inputs and outputs, extensive audio routing, mixing and effects capabilities. A complete circuit description, schematic diagram and bill of materials are also included.
  • Page 2 Windows™ operating system (Win2000 or XP). Introduction The TLV320AIC33EVM is in Texas Instruments' modular EVM form factor, which allows direct evaluation of the device performance and operating characteristics, and eases software development and system prototyping. This EVM is compatible with the 5-6K Interface Evaluation Module (SLAU104) and the HPA-MCUINTERFACE (SLAU106) from Texas Instruments and additional third-party boards which support TI's Modular EVM format.
  • Page 3: Analog Interface

    Analog Interface Analog Interface For maximum flexibility, the TLV320AIC33EVM is designed for easy interfacing to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin dual row header/socket combination at J13 and J14. These headers/sockets provide access to the analog input and output pins of the device.
