What is BS EN IEC 62680-1-5- Universal serial bus interfaces for data and power about?
The IEC 62680 series is based on a series of specifications that were originally developed by the USB Implementers Forum (USB-IF).
BS EN IEC 62680-1-5 is an International Standard that discusses universal serial bus interfaces for data and power. 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 purpose of BS EN IEC 62680-1-5 is to describe the minimum capabilities and characteristics an audio device shall support to comply with the USB. BS EN IEC 62680-1-5 also provides recommendations for optional features.

- Product designers
- Quality control authorities
Why should you use BS EN IEC 62680-1-5- Universal serial bus interfaces for data and power?
In principle, a versatile bus specification like the USB provides many ways to propagate and/or control digital audio. For the industry, however, it is very important that audio transport mechanisms be well defined and standardized on the USB. Only in this way can interoperability be guaranteed among the many possible audio devices on the USB. Standardized audio transport mechanisms also help to keep software drivers as generic as possible. The Audio Device Class described in BS EN IEC 62680-1-5 satisfies those requirements.
BS EN IEC 62680-1-5 contains all necessary information for a designer to build a USB-compliant device that incorporates Audio Functionality. It specifies the standard and class-specific descriptors that shall be present in each USB Audio Function.
It further explains the use of class-specific requests that allow for full Audio Function control. A number of predefined data formats are listed and fully documented. Each format defines a standard way of transporting audio over the USB. Provisions have been made so that vendor-specific audio formats and compression schemes can be handled as well.
