ABSTRACT:
A serial interface bus system for transmitting and receiving a plurality of bus signals which collectively allow communication of data between a digital audio source (12, 22, 24, 26, 56, 82) such as a compact disc and a digital sink (42, 52, 62, 64, 66) such as a digital signal processor. The plurality of bus signals provided by the interface bus system allow many different audio sources and sinks to be used without glue logic. The plurality of bus signals allow multiple transceivers to be configured in a daisy chain (20, 60) wherein a master is selectively chosen to optimize performance of such a system. The daisy chain configuration may be implemented to provide digital data to a wide variety of storage circuits for digital information.
