DSD on SDIF-2 -
An SDIF-2 interface can be used for DSD. The waveforms appear quite different
to PCM format. However, they do produce transitions where the illegal code
transitions were, and for this reason we advise against locking to the illegal
transitions in SDIF-2. We recommend always using Word Clock with SDIF-2
signalling.

DSD on SDIF-3 -
SDIF-3 embeds a clock in the SDIF-2 data stream, and so does not need word
clock. It is used only for DSD – it is not used for PCM. Contact SONY for more
details.
