Not Recommended For New Designs PCM2900B PCM2902B SLES229 – DECEMBER 2008 ........................................................................................................................................................................................... www.ti.com DEVICE CONFIGURATION Figure 31 illustrates the USB audio function topology. The PCM2900B/2902B has four interfaces. Each interface consists of alternative settings.
PAGE 21
Not Recommended For New Designs PCM2900B PCM2902B www.ti.com ........................................................................................................................................................................................... SLES229 – DECEMBER 2008 Interface #0 Interface #0 is defined as the control interface. Alternative setting #0 is the only possible setting for interface #0. Alternative setting #0 describes the standard audio control interface.
PAGE 22
Not Recommended For New Designs PCM2900B PCM2902B SLES229 – DECEMBER 2008 ........................................................................................................................................................................................... www.ti.com Interface #2 Interface #2 is the audio streaming data-in interface. Interface #2 has the 19 alternative settings listed in Table 7. Alternative setting #0 is the zero bandwidth setting.
