TMS320C5535: USB Audio inquiry

Part Number: TMS320C5535

HelloTeam,

My customer would like to know what are the characteristics or limitations of USB audio drivers for this part? Will it recognize a request from a 32 bit/384kHz source and pull + pass the USB Audio source content to the next stage uncompressed? Or is there a 16bit 48kHz limit? Or something else?

What USB interface is this device allowing for and or capable of.

Regards,

Renan

  • Hi Renan,

    The current USB Audio Class 1.0 supported on C5535 is limited by the USB speed (Full speed). It is 12Mbps, 32bit at 384khz is 12.288Mbps which is over the 12Mbps limit. The 16 bit at 48khz is 768Kbps is OK.

    Best regards,

    Ming
