Interfaces de bus série universel (USB) pour les données et l'alimentation électrique - Partie 4-1: Spécification du bus série universel 4 ™
L'IEC 62680-4-1:2022 contient des spécification du bus universel en série 4™ L'USB 3.1 et l'USB 3.2 ont constitué des étapes évolutives visant à augmenter la bande passante. L'objectif de l'USB4 reste le même, avec l'objectif supplémentaire d'aider à converger l'écosystème de connecteurs USB Type-C® et de réduire autant que possible la confusion pour l'utilisateur final. Plusieurs aspects de conception essentiels pour atteindre cet objectif sont répertoriés ci-dessous: • offrir une fonctionnalité d'affichage, de données et de charge/stockage sur un seul connecteur USB Type-C; • maintenir la compatibilité avec l'écosystème existant de produits USB et Thunderbolt™; • définir les capacités de port pour produire une expérience utilisateur prévisible et cohérente; • fournir davantage de flexibilité à l'hôte pour configurer la bande passante, la gestion de l'alimentation et d'autres paramètres liés aux performances pour les besoins du système. Inclut les errata et ECN au 19 mai 2021 dans le texte de la spécification.

UNIVERSAL SERIAL BUS INTERFACES FOR DATA AND POWER
Part 4-1: Universal Serial Bus 4™ Specification
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical
Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations
liaising with the IEC also participate in this preparation. IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The IEC 62680 series is based on a series of specifications that were originally developed by the USB
Implementers Forum (USB-IF). These specifications were submitted to the IEC under the auspices of
a special agreement between the IEC and the USB-IF.
This standard is the USB-IF publication, USB4™ Specification, Version 1.0 with Errata and ECN
through May 19, 2021.
The USB Implementers Forum, Inc.(USB-IF) is a non-profit corporation founded by the group of
companies that developed the Universal Serial Bus specification. The USB-IF was formed to provide
a support organization and forum for the advancement and adoption of Universal Serial Bus
technology. The Forum facilitates the development of high-quality compatible USB peripherals
(devices), and promotes the benefits of USB and the quality of products that have passed compliance
testing.
