Solving Enumeration Errors in USB Audio DAC and CODEC Designs
PDF, 157 Kb, Datei veröffentlicht: Oct 30, 2009
TIвЂ™s portfolio of audio digital-to-analog converters (DACs) and coder/decoders (codecs) with integrated USB interfaces offers an excellent building block for any streaming USB audio system. When designing with the PCM270x and PCM29xx devices, careful attention must be given to both the clocking and USB hardware configurations in order to ensure proper host to device communication.This applicatio

Audio Serial Interface Configurations for Audio Codecs
PDF, 70 Kb, Datei veröffentlicht: Sep 22, 2010
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 (О”ОЈ) architecture require an internal master clock
