English term or phrase: interpair spacing
Bonjour,

Dans un article d'électronique sur les différents types de mémoire, destiné à des ingénieurs, je trouve deux termes "interpair spacing" et intrapair spacing" comme caractéristique de la conception d'une carte électronique (pour éviter les interférences etc.), allant de pair avec la largeur des pistes par exemple.

Voici l'extrait :

"DDR designs also need to pay attention to other specifications, like tight tolerances on reference, source and termination voltages, appropriate decoupling, layout considerations like trace widths, interpair spacing and intrapair spacing and trace routing."




J'ai trouvé une définition en anglais de chacun des termes indiqués dans un doc sur le net, mais je n'arrive pas à trouver une traduction fiable en français.

Voici le lien vers le doc : https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&c...



Les deux définitions sont les suivantes :

Interpair spacing (S1) is the distance between two adjacent traces within a related set of signals with similar or equivalent functionality. The control signals group, clocks, address bus, data bus, and data/strobes are all signal sets. The data bus is sometimes broken down into data bytes, which are sets of eight signals, and the associated strobe and mask signal.

Intrapair spacing (S2) is the distance between the two outermost signals of different sets. For example, if the control signal set is routed together and adjacent to the address signal set, intrapair spacing is the distance between the two individual signals from control and address sets that are closest together.




Merci d'avance pour toute aide ou début de piste.

disagree  Tony M: Yes, but this misses out the vital 'pair' — otherwise, inter/intra has no sense.

disagree  FX Fraipont: nothing to do with letter spacing in Adobe inDesign - this is about PCBs

neutral  Thomas Miles: À défaut d'un terme officiel, je ne vois pas pourquoi cette solution ne serait pas acceptable. Ce serait utile peut-être de préciser ce qui constitue les paires (signaux? ensembles?).
