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.
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.

USB Host The USB interface to the host computer system is referred to as the Host
Controller. The Host Controller may be implemented in a combination of
hardware, firmware or software. A ‘root hub’ is integrated within the host
system to provide one or more attachment points. Additional information
concerning the ‘USB host’ may be found in Section 4.9 and Chapter 10 of
the USB Specification USB 2.0.
USB Topology The USB connects USB devices with the USB host. The USB physical
interconnection is a tiered star topology. A ‘hub’ is at the center of each
star. Each wire segment is a point-to-point connection between the ‘host’
and a ‘hub’ or ‘function,’ or a ‘hub’ connected to another ‘hub’ or ‘function.’

Note 1: Impedance, Propagation Delay and Skew Test Fixture. This fixture will be used with the TDR for
measuring the time domain performance of the cable under test. The fixture impedance should be matched to the
equipment, typically 50Ω. Coaxial connectors should be provided on the fixture for connection from the TDR.
Note 2: Attenuation Text Fixture. This fixture provides a means of connection from the network analyzer to the
Series ‘A’ plug. Since USB signals are differential in nature and operate over balanced cable, a transformer or
balun (North Hills NH13734 or equivalent) is ideally used. The transformer converts the unbalanced (also known as
single-ended) signal from the signal generator which is typically a 50Ω output, to the balanced (also known as
differential) and likely different impedance loading presented by the cable. A second transformer or balun should
be used on the other end of the cable under test to convert the signal back to an unbalanced form of the correct
impedance to match the network analyzer.
