XMOS USB Audio Support 384kHz?

Post by licall »

Hi,

Currently the XMOS USB Audio 2.0 Reference Design supports bit perfect audio data up to 384KHz or not yet? both XMOS Device and PC Driver?

thanks,

Licall

Out of the box, no. It can be added relatively simply.

The main issue is that there are no XMOS boards with 384kHz capable DACs

We'll most likely be adding the capability for the next release, but I do not believe there are plans to provide a generally available board with 384kHz support since it requires a fairly specialised DAC which would push up price and complexity for other users (that are not interested in 384kHz).

Yes, I download the source code "sw_usb_audio_6.0.0beta8(1.0)[12.0.0]", and have Change the Firmware to support 384kHz sampling rate.
But the DAC do not support 384kHz.
I'm plan to make a DAC board which the DAC chip is PCM5102-Q, from TI.

I made a 384K board several days ago, still have some issue.

If you want some help, you are going to have to elaborate I'm afraid. Unless you mean you have issues with you board..
