This document and its associated files (MSP430 Audio Boot Code - SLAC640) give a foundation for customers to use the MSP430 Launchpad as a tool to evaluate and demonstrate TI Audio products, without the need to be connected to a computer. This application code will take header files exported from TI Audio development tools and create standalone, bootable demo’s – using the MSP430 as a host.

his report discusses the phenomenon of out-of-band noise, and examines the results of the out-of-band noise measurements for audio codecs. Frequency spectrum measurements were done on the TLV320AIC33 to analyze the output out-of-band noise. FFTs were captured for the HPOUTs in various conditions to demonstrate the effects of filtering for measurement purposes

An audio serial interface (ASI) provides a means to transfer non-buffered audio data between processors and/or audio converters. These data are typically encoded in PCM twos complement format, although other format variations may be possible to achieve companding for lower data rate transfers. Audio converters based on the delta-sigma (ΔΣ) architecture require an internal master clock that operates at a much faster rate than the target sample rate. Although there are several means to obtain this master clock, care must be taken to ensure that this clock does not drift with respect to the ASI. This report discusses several configurations that prevent such situations.

his user's guide describes the characteristics, operation, and use of the TLV320AIC29EVM, both by itself and as part of the TLV320AIC29EVM-PDK. This evaluation module (EVM) is a complete stereo audio codec evaluation module, with several audio inputs and outputs, side tone, key click, and effects capabilities. A complete circuit description, schematic diagram and bill of materials are also included
