Digital patchbay

[Martin Czech]

I think max. F is  3 MHz.  Even CDxxxx muxers should handle that, may
be not at 5V.  A muxer will allways weaken the signal drive, so perhaps
a bus structure with tristate drivers is better.  All z but one, which
is the talker.

Should be not critical layout, if the pcb lines get long, you'll have to
terminate the ends, groundplane recommended.

AES/EBU has unfortunately a different format than SPDIFF.  Simple hardware
won't do in this case.

m.c.
