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 - Low Sampling Rate Operation SoundPlus Audio Data Converters and CODECsPDF, 291 Kb, 档案已发布: Sep 27, 2000
This application bulletin describes the operation and performance of Burr-Brown's PCM digital audio products when using low sampling frequencies. - Control Port And Reset Operation SoundPlus Audio Converters and CODECsPDF, 77 Kb, 档案已发布: Sep 27, 2000
This application bulletin provides operational details of the serial control port and reset functions for Burr-Brown digital audio data converters and CODECs. Specifically, this information applies to the PCM1716, PCM1717, PCM1719, PCM1720, PCM1723, PCM1727, PCM3000-series CODECs, and the PCM1800 A/D converter. - Solving Enumeration Errors in USB Audio DAC and CODEC DesignsPDF, 157 Kb, 档案已发布: Oct 30, 2009
TI’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
