[sdiy] Biphase Mark (OT)

[Jay Schwichtenberg]

Alex,

Are you doing the SPDIF logic yourself? If you are buy a chip from Crystal
or AKM and save yourself some big headaches.

Most SPDIF output chips I've used take a transformer and maybe some
resistors or caps. Check out some of the SPDIF data sheets, eval boards and
app notes from Crystal Semiconductor. I haven't looked at the AKM sheets in
a while and can't remember if they have interface stuff in their
documentation.
