  • Control Port And Reset Operation SoundPlus Audio Converters and CODECs
    PDF, 77 Kb, Archivo publicado: sept 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.
  • Configuring I2S to Generate BCLK from Codec Devices & WCLK from McBSP Port
    PDF, 105 Kb, Archivo publicado: jul 8, 2009
    This application note describes a method for interfacing the multichannel buffered serial port (McBSP) to the IВІSв„ў interface of the TLV320AIC32/33/31, theTLV320AIC3101/3104/3105/3106/3204/3254 and TLV320DAC32 devices such that the bit clock (BCLK) is generated by the audio data converter device and the word clock (WCLK) is generated by the McBSP.This type of interface is useful in applications

  • Solving Enumeration Errors in USB Audio DAC and CODEC Designs
    PDF, 157 Kb, Archivo publicado: 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
  • Audio Serial Interface Configurations for Audio Codecs
    PDF, 70 Kb, Archivo publicado: sept 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
