The PCM2903B is ready for setup when the reset sequence has finished and the USB bus is attached. In order

to perform certain reset sequences defined in the USB specification, VDD, VCCC, VCCP1, VCCP2, and VCCX must rise

up within 10 ms / 3.3 V. After connection has been established by setup, the PCM2903B is ready to accept USB

audio data. While waiting, the audio data (idle state) and analog output are set to bipolar zero (BPZ).

When receiving the audio data, the PCM2903B stores the first audio packet, which contained 1-ms audio data,

into the internal storage buffer. The PCM2903B starts playing the audio data when detecting the next start of

frame (SOF) packet, as illustrated in Figure 35 and Figure 36.
