Part Number: PCM2902C

Hi Sir,

May I know the PCM2902C can support transmitting and receiving the audio data at the same time on the USB port?

    Hello,

    The PCM2902C devices support the Isochronous USB Audio format.  Isochronous Transfers are used for transmitting real-time information such as audio and video data, and must be sent at a constant rate. USB isochronous data streams are allocated a dedicated portion of USB bandwidth to ensure that data can be delivered at the desired rate.

    Take a look at the Interface#0 - #3 information starting on page 21 of the datasheet.
