Hi, I've just starting studying about LVDS signals and i got a little confused.. When we say they are referenced to each other does it mean that ground return path is not needed? For example, i want to transfer an LVDS signal from one pcb to another through a cable, a twisted pair is enough? Or do i need an extra wire for ground connection?

A twisted pair will do but for optimum noise immunity, you need a screened cable.
