Abstract
Data bus includes a device controller coupled to a first interface for digital communications using a first communications protocol, the device controller including a master bus controller controlling a multi-drop bus using a second communications protocol, and a slave device coupled to the multi-drop bus and configured to transmit and receive digital communications with the device controller using the second communications protocol. Each transmission line end is terminated using a device attached at one end of the transmission line and by another device attached at the other end. The second communications protocol supports multiple data rates using a fixed frame format. Safe synchronization may be established by systematically eliminating all false positions instead of searching for a valid candidate. Noise in the audio band may be lowered by scrambling of the data using a pseudo-random generator.
