标准摘要
[中文适用范围]： IEC 60958的这一部分规定了不同介质的物理和电气参数。本部分与 IEC 60958-1、IEC 60958-4-1 和 IEC 60958-4-2 一起指定了一种接口，用于将两个通道的周期性采样和线性表示的数字音频数据从一个发送器串行数字传输到一个接收器。 IEC 60958-1 中定义的传输格式旨在与传统设计的屏蔽双绞线一起使用，传输距离可达 100 m，无需在接收器处进行传输均衡或任何特殊均衡，帧速率高达 50 kHz。可以使用更长的电缆长度和更高的帧速率，但对电缆选择和可能的接收器均衡或有源中继器的使用或两者的谨慎要求迅速增加。该标准规定平衡终端采用75同轴电缆，并正在考虑采用光纤电缆传输。该标准不涵盖与任何公共运营商设备的连接。在这个接口规范中，还提到了供消费者使用的接口。这两个接口并不相同。 [外文原描述]： IEC 60958-4-4:2016 specifies the physical and electrical parameters for different media. This part together with IEC 60958-1, IEC 60958-4-1, and IEC 60958-4-2 specify an interface for the serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver. This first edition, together with IEC 60958-4-1 and IEC 60958-4-2, cancels and replaces the IEC 60958-4 published in 2003 and its Amendment 1:2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60958-4:2003 with its Amendment 1:2008: - support for a wider range of physical media; - support for a wider range of audio sampling frequencies; - deprecation of "minimum implementation" of channel status data.
