Thanks for pointing out my errors! And doing so nicely.
I picked up some poor info from somewhere.
I'm very familiar with synchronous data transmission where digital data is present on one conductor and its associated clock is present on a separate conductor; but SPDIF can't be exactly like that as there is only one conductor (not counting the earth screen). Though there are alternatives to SPDIF where the clock is sent on its own conductor; I think the Accuphase proprietary interface does this, and I think there are others.
I can perhaps only add that the 'analogue' performance of the SPDIF transmission may matter significantly, as I see several references to 'eye pattern' relevant to SPDIF; and 'eye pattern' is familiar to me regarding modem signals. And the 'fuzz' or blurring around the points of a modem eye pattern are ... guess what ... jitter.
Or perhaps I'm still confused! :-)
Anyway, Belden 89259 does make a *very* good SPDIF cable ...
