In Reply to: Cable length determines arrival time of reflections. posted by Al Sekela on November 19, 2008 at 14:19:06:
"If cable length matters, then the problem is signal reflections from the cable ends. Making the cable longer makes the reflections arrive later in time."
Yes, that's what I've heard.
"The issue is impedance matching."
If devices at both ends of the cable have 75ohm termination resistance and the cable is 75ohm with 75ohm connectors, how is that an impedance mis-match?
Of course, with AN we're not dealing with 75ohm cable or connectors. The transports and DACs are all 75ohm DI/O, I believe.
