Hi everyone! I have a motherboared which sends 2 pairs of LVDS signals to a daughterboard through ffc cable. My question is, the receiver at daughterboard should it be supplied by vdd and ground coming from the original source of LVDS's signals(e.g. motherboard)? And if so, what is the minimum distance I should keep between LVDS lines and vdd & gnd? I know that for TTL signals a rule of thump is 3*S, where S is the distance between the lines of an LVDS pair, but since we are talking about dc voltage and there are no high transition times, is it ok if I use adjacent wires of the ff cable?
