I²S is a digital interface specification designed to reduce errors (jitter and suchlike) compared with the more common S/PDIF interface found on most equipment. The I²S interface splits the clock and data signals in an attempt to reduce errors, where the S/PDIF interface uses one conductor and is more susceptible to crosstalk interference between the data and clock portions. Not yet common. Regards, Richard at www.vantageaudio.com
