Termination Resistors for PCM bus
Termination Resistors for PCM bus
(OP)
I have an app that uses a 24" cable with multiple connectors at different intervals on it. It carries a digital audio PCM bus and other signals. The PCM signals are only used on 6" of the cable, from there to the other end they are currently left floating. My question is should I terminate them at the floating end, and if so what resistance?

But this is a question of bandwidth too. Do you have a scope? Depending on the rise time of the signals, you may not even need terminations and still have a good signal quality.
Is it a flat cable? Can you just cut the PCM conductors just after your connector?
