Abstract
A data transmission system for use in hearing devices includes a master unit with a first local bit clock and a slave unit with a second local bit clock. The master unit and the slave unit are connected to each other via a bus line, and are configured to communicate over the bus line according to a communication protocol based on a frame-wise serial transmission of bits. Each frame includes a clock reference, a master signalling interval, a slave signalling interval and a data payload. The slave unit further includes a clock recovery device for synchronizing the second local bit clock with the first local bit clock based on the clock reference transmitted once per frame by the master unit. A corresponding method for data transmission is also provided. Moreover, hearing devices including such a data transmission system as well as uses of such a method for data transmission are proposed.
