Keysight a lanc\u00e9 une plate-forme de conformit\u00e9 des \u00e9metteurs pour l’Ethernet optique automobile, ciblant les PHY nGBASE-AU selon la norme IEEE 802.3cz<\/a>. La solution AE6980T s’appuie sur FlexDCA et est positionn\u00e9e pour valider les liens optiques multi-gigabits utilis\u00e9s dans les r\u00e9seaux de v\u00e9hicules par zones et d\u00e9finis par logiciel, o\u00f9 l’Ethernet optique automobile gagne du terrain.<\/p>\n

Pour les lecteurs d’ECInews, ceci est pertinent car Keysight<\/a> a d\u00e9voil\u00e9 le syst\u00e8me lors de la journ\u00e9e technologique Ethernet & IP @ Automotive de l’IEEE \u00e0 Toulouse, en France, et parce que les constructeurs automobiles europ\u00e9ens et les Tier-1 \u00e9valuent activement l’IEEE 802.3cz pour les backbones embarqu\u00e9s \u00e0 large bande passante et r\u00e9sistants aux interf\u00e9rences \u00e9lectromagn\u00e9tiques (EMI).<\/p>\n

Ce que la plateforme couvre<\/h2>\n

La solution de test d’\u00e9metteur AE6980T<\/a> nGBASE-AU se concentre sur la qualit\u00e9 du signal de l’\u00e9metteur et la conformit\u00e9 automatis\u00e9e. Elle int\u00e8gre un flux de travail TDFOM (Transmitter Distortion Figure of Merit) dans FlexDCA pour permettre des \u00e9valuations de la qualit\u00e9 visuelle et de la marge, ce qui peut raccourcir les cycles de d\u00e9bogage et de corr\u00e9lation pour les laboratoires et les maisons de test. Les configurations prises en charge comprennent le DCA-M N1092A\/N1092C de Keysight avec r\u00e9cup\u00e9ration d’horloge via le N1077B.<\/p>\n

Selon les documents de Keysight, cette version s’aligne sur les sp\u00e9cifications IEEE 802.3cz et Open Alliance TC7 test-house, et automatise la g\u00e9n\u00e9ration de rapports pour les \u00e9quipes d’ing\u00e9nierie. Ces fonctionnalit\u00e9s sont con\u00e7ues pour aider les d\u00e9veloppeurs de liaisons optiques embarqu\u00e9es \u00e0 haut d\u00e9bit, allant de 2,5G \u00e0 50G sur fibre multimode, \u00e0 atteindre les \u00e9tapes du programme avec une plus grande confiance.<\/p>\n

Normes et collaboration<\/h2>\n

L’IEEE 802.3cz d\u00e9finit l’Ethernet optique automobile multi-gigabit avec une faible latence et une immunit\u00e9 aux interf\u00e9rences \u00e9lectromagn\u00e9tiques, des caract\u00e9ristiques potentiellement int\u00e9ressantes pour les architectures zonales et l’agr\u00e9gation de capteurs ADAS. Les informations de presse soulignent que les liaisons optiques constituent un \u00ab\u00a0facilitateur essentiel\u00a0\u00bb \u00e0 mesure que les architectures E\/E des v\u00e9hicules se centralisent.<\/p>\n

Keysight note une collaboration avec KD sur le d\u00e9veloppement de l’IEEE 802.3cz et les sp\u00e9cifications de test TDFOM, ce qui indique un alignement croissant de l’\u00e9cosyst\u00e8me autour de l’Ethernet automobile optique et de la caract\u00e9risation des dispositifs nGBASE-AU.<\/p>\n","protected":false},"excerpt":{"rendered":"
