This International Standard describes an application of a serial, uni-directional, self-clocking interface as defined in IEC 60958-1, for the interconnection of digital audio equipment for professional applications.The interface is primarily intended to carry monophonic or stereophonic programmes, at a 48 kHz sampling frequency and with a resolution of up to 24 bits per sample. It may alternatively be used to carry signals sampled at 32 kHz or 44,1 kHz.The format is intended for use with shielded twisted-pair cables over distances of up to 100 m without transmission equalization or any special equalization at the receiver. Longer cable lengths may be used with cables better matched for data transmission, or with receiver equalization, or both.In both cases, the clock references and auxiliary information are transmitted along with the audio data. Provision is also made to allow the interface to carry non-audio data.
