Abstract: A method of operating a clock circuit can include transmitting a clock signal from a transmitter of a first system to a receiver of a second system, where a first repeating edge of a clock cycle of the clock signal repeats at a predetermined constant frequency within the clock signal to synchronize operations of the second system, and varying, by the first system, a second edge within the clock cycle of the clock signal to transmit a data transmission within the clock signal.

Abstract: A method of synchronizing operations between integrated circuits can include transmitting a first clock signal from a first transmitter associated with a first integrated circuit of a first system, to a receiver associated with a second integrated circuit of a second system, receiving a second clock signal from a second transmitter associated with a third integrated circuit of the second system, receiving at the first system a first phase difference determined by the second system, wherein the first phase difference is determined between the first clock signal at the second system and the second clock signal at the second system, determining a second phase difference at the first system, wherein the second phase difference is determined between the first clock signal at the first system and the second clock signal at the first system, and determining a difference between the first phase difference and the second phase difference.
