Abstract:
A method for initiating a serial data stream between a transmitter and a receiver, wherein the transmitter operates according to at least a first clock having a first clock rate, wherein the receiver operates according to at least a second clock having a second clock rate, wherein a ratio between the second clock rate and the first clock rate is an integer number greater than or equal to one, the method comprising:providing a first state over a serial line between the transmitter and the receiver; providing one or more start bits over said serial line, wherein said one or more start bits indicate a second state different from said first state; providing one or more ratio bits over said serial line after said start bit, wherein said one or more ratio bits indicate said ratio between the second clock rate and the first clock rate; receiving said one or more start bits; using a transition between said first state and said second state to receive said one or more ratio bits; and receiving a remainder of said serial data stream at intervals of said second clock rate.
