Universal serial bus interfaces for data and power - Part 1-8: Common components - USB Audio 3.0 device class definition terminal types
SIST EN IEC 62680-1-8:2020

IEC 62680-1-8:2019 is to describe in detail all the Terminal Types that are supported by the Audio Device Class. This document is considered an integral part of the Audio Device Class Specification, although subsequent revisions of this document are independent of the revision evolution of the main Audio Device Class Specification. This is to easily accommodate the addition of new Terminal Types without impeding the core Audio Device Class Specification. The Audio Device Class Definition applies to all devices or functions embedded in composite devices. All audio signals inside an audio function start at an Input Terminal, pass through some Units, and leave the function through an Output Terminal. Units can manipulate the signal in various ways. Terminals represent the connections of the function to the outside world. As part of the Terminal descriptor, the wTerminalType field specifies the vendor’s suggested use of the Terminal. For example, a pair of speakers is a more suitable target for music output than a telephone line. This feature allows a vendor to ensure that applications use the device in a consistent and meaningful way.

Universal serial bus interfaces for data and power - Part 1-5: Common components - USB Audio 3.0 device class definition

IEC 62680-1-5:2019 describes the minimum capabilities and characteristics an audio device shall support to comply with the USB. This document also provides recommendations for optional features.
The Audio Device Class Definition applies to all devices or functions embedded in composite devices that are used to manipulate audio, voice, and sound-related functionality. This includes both audio data (analog and digital) and the functionality that is used to directly control the audio environment, such as Volume and Tone Control. The Audio Device Class does not include functionality to operate transport mechanisms that are related to the reproduction of audio data, such as tape transport mechanisms or CD-ROM drive control.

Universal serial bus interfaces for data and power - Part 1-8: Common components - USB Audio 3.0 device class definition terminal types

IEC 62680-1-8:2019 is to describe in detail all the Terminal Types that are supported by the Audio Device Class. This document is considered an integral part of the Audio Device Class Specification, although subsequent revisions of this document are independent of the revision evolution of the main Audio Device Class Specification. This is to easily accommodate the addition of new Terminal Types without impeding the core Audio Device Class Specification.
The Audio Device Class Definition applies to all devices or functions embedded in composite devices. All audio signals inside an audio function start at an Input Terminal, pass through some Units, and leave the function through an Output Terminal. Units can manipulate the signal in various ways. Terminals represent the connections of the function to the outside world.
As part of the Terminal descriptor, the wTerminalType field specifies the vendor’s suggested use of the Terminal. For example, a pair of speakers is a more suitable target for music output than a telephone line. This feature allows a vendor to ensure that applications use the device in a consistent and meaningful way.

Communication cables - Specifications for test methods - Part 1-9: Electrical test methods - Unbalance attenuation (transverse conversion loss TCL transverse conversion transfer loss TCTL)
EN 50289-1-9:2017

This draft European Standard details the test methods to determine the attenuation of converted differential-mode signals into common-mode signals, and vice versa, due to balance characteristics of cables used in analogue and digital communication systems by using the transmission measurement method. The unbalance attenuation is measured in, respectively converted to, standard operational conditions. If not otherwise specified, e.g. by product specifications, the standard operational conditions are a differential-mode which is matched with its nominal characteristic impedance (e.g. 100 Ω) and a common-mode which is loaded with 50 Ω. The difference between the (image) unbalance attenuation (matched conditions in the differential and common-mode) to the Betriebs- (operational) unbalance attenuation (matched conditions in differential-mode and 50 Ω reference load in the common-mode) is small provided the common-mode impedance Zcom is in the range of 25 Ω to 75 Ω.
For cables having a nominal impedance of 100 Ω, the value of the common-mode impedance Zcom is about 75 Ω for up to 25 pair- count unscreened pair cables, 50 Ω for common screened pair cables and more than 25 pair- count unscreened pair cables, and 25 Ω for individually screened pair cables. The impedance of the common-mode circuit Zcom can be measured more precisely either with a time domain reflectometer (TDR) or a network analyser. The two conductors of the pair are connected together at both ends and the impedance is measured between these conductors and the return path.
This draft European Standard is bound to be read in conjunction with prEN 50289-1-1, which contains essential provisions for its application.
