1 Liaisons séries à haute vitesse Pr. F. Vannel LPSCP

2 Liaisons séries haute vitesse But Transmission séries sur paire différentielles Débit par ligne (~1Gb/s à 28 Gb/s) Horloge + Data sur la même paire Synchronisation des données 2

3 Applications Applications informatiques PCIe USB 3.0 SATA HDMI Télécommunications Ethernet simple paire1gb/s, 10Gb/s Ethernet multi-paire 40Gb/s (4x10Gb/s), 100Gb/s (10x10Gb/s, 4x25Gb/s) Cryptographie quantique Applications spécifiques Analyseur logique Time to Digital converter Communications inter-circuits 3

4 Un peu d histoire Les bus parallèles Exemple d applications informatiques PCI 2.2 (le plus répandu) Grand public : MHz à Bande passante 133 MB/s Professionnel : MHz à Bande passante 528 MB/s PCI-X MHz à Bande passante 1066 MB/s IDE 16 bits à Bande passante 133 MB/s (U-DMA Imprimante (parallèle). Plus vite? 4

5 Limitations des bus parallèles Problèmes électriques 1. Couplage électrique capacitif (crosstalk) ayant des effets notables dès distance > ~10 cm 2. Clock skew : retard à l arrivée entre différentes bascules contrôlées par la même horloge 3. Jigue (Jitter) : fluctuation temporelle sur les signaux à Difficulté de transmettre des signaux par bus parallèle sur câble de longueur de plusieurs dizaines de cm essentiellement à cause du crosstalk 5

6 Bus série plus rapide que bus parallèle? Bus parallèle Nombre de signaux n 1 Bus série Fréquence f Max ~100 MHz Max ~10 GHz Utilisation DDR (dual data rate) Coût fabrication du câble (cuivre) Non recommandé (crosstalk) Proportionnel au nombre de signaux n Oui faible Bande passante n x f 1 ligne x f x 2 (DDR) 6
