Word clock spec

[JulienG]

Does anyone have a copy?

I'm considering an experiment using a signal generator to generate word clock referenced off my shiny new (well, old) GPS reference clock, which, when synced with the GPS constellation maintains ~1x10^-13 accuracy, rather better then most audio clocks.

However I'm fairly sure word clock is actually a little more complex then that.

Something like the Antelope Audio clocks, albeit (in theory) more accurate.
