Hi,
If by "x200 development board" you mean the xCORE-200 Multi Channel board then the converters on this board support a maximum sample rate of 192 kHz.
The MC board already supports S/PDIF optical/coaxial optical input and output.
The best place to start, to learn about the USB audio reference design is the Design Guide : https://www.xmos.com/published/usb-audio-software-design-guide.
Best regards,
John

Hi John, so the question is being that my PCM5x DAC can process 384k and I typed it into the firmware, should it show up on the TUSB driver as accepting that? As so far that doesn't appear to work. Thanks

You might like to review this discussion : http://www.xcore.com/viewtopic.php?t=4375. In particular Ross' comment that 384k is only supported under WIndows with ASIO.

I want to go for the 3 osc approach, I have the MUX from the dev board already in my schematic and can connect it to the FSEL pin. My next question is how do I connect these osc's to the XMOS chip, and to the MUX inputs?

When using osc's so far I just rig them up to the XTAL pins of the chip in question, IE the PLL or an MCU. So how do I configure a schematic circuit for connecting the osc's directly to the x200 XMOS chip, and also the inputs of the MUX in question?

Thanks!

The following should do the trick but welcome confirmation from other developers / XMOS staff:

PS: Not looking for a Russian bride at this time but is it possible to host the uploads onto Amazon or a higher class / quality website ?

The ADCs and DACs on the multi channel audio card only supports sampling rates up to 192 kHz. If you wish to support 384 kHz you will need to use different converters.

An old thread but noting for closure that this part is active again through distribution under the Microchip brand:

Manufacturer Part #: PL611-01-N12MC

Ah great. How does one program this device. Obviously choosing your crystal as the reference but how do you set the remaining 5, 8 and 10 bit values or are they always constant values? i.e can I just put this part into the existing design or does it need some additional programming first?
