US Patent 7106793 Method, device, and interface for transmitting data

A method, a device, and an interface for transmitting data between at least two subscribers, at least one first subscriber transmitting a pulse-width-modulated data signal. The at least second subscriber for its part transmits an asynchronous data signal, which is composed of binary signals, both subscribers transmitting the data, in each case, at a different, specifiable transmission rate. In this context, one of the two transmission rates, in particular that of the second subscriber, is adjusted, in particular increased, so that the pulse-width-modulated data signal of the first subscriber is simulated by a number of the binary signals of the asynchronous data signal.
