S/PDIF support on Beagleboard or equivalent

Hi all,

I've been working on a project involving S/PDIF digital audio output
from a Beagleboard. For now I'm successfully using a Lindy USB adapter
but in future we'll need this functionality on the board.

Can anybody suggest an appropriate mechanism for adding S/PDIF to
the Beagleboard, perhaps via a module? (or is there a Beagleboard clone
that has S/PDIF?).

and we may have to hook on some kind of I2S->S/PDIF or PCM->S/PDIF IC
to one of the mcBSP pins (???)

Preferably we'd like to be able to add a module, but if a board re-spin
is needed can anybody recommend experienced OMAP3530/ Beagleboard
hardware development houses we might approach?

Thanks,

The -xM has access to the McBSP that is used for the audio. This is the McBSP (I2S) that has the large buffer size. So, it would be possible for you to do an add on board for the -xM to give you what you need. There are I2S to SPDIF devices out there, so that in my mind would be your best solution for an add on board.

Thanks Gerald - good to know that I’d need to look at the -xM to progress this.

Best Regards,

I actually did an SPDIF interface once before and I looked to see what I had used, but I can’t seem to find the information.
