Hi,
I am thinking about the best way to transmit 5 single ended signals from one board to another as well as ground and 2 power rails. I was thinking cat5e cable with a standard rj45 plug but as cat5e is twisted pair I’m concerned about crosstalk.
The cable between the two boards would be a maximum of 50cm. 3 of the signals are addresses for a multiplexer that would change at a maximum speed of 2ms per change. One of the other signals is a 20khz pwm signal. The final signal is a zc detector for mains so max Freq of 100/120hz.
There may be high current switches at ac line frequency (50/60hz) near by.
Would single ended transmission with cat5e cable be okay for this or would I need differential signalling? If I need differential signalling, what sort of cable/connector could I use?
Any help is appreciated
Thanks
