I need to send a 40 MHz clock (18V PP) 30 to 45 cm (12 to 18 inches). What kind of cable should I use (i.e., does it need to be shielded and how should it be terminated)?
A question on a different matter, I need a reset signal for multiple devices with a total cable length of about 2 to 3 meters. Will regular cable work (24 AWG) or do I need a shielded cable or perhaps a differential signal? If it does not need to be a differential signal does it make a difference if it is active high or active low? A reset occurs only about once every few seconds at the most. I know a differential signal would be best, but I am trying to keep the pin count on my connectors as low as possible.
