Abstract
A method for transferring first and second encoded client clock signals over a carrier clock domain between integrated circuits, including in a first integrated circuit encoding a phase change of the first client clock signal from a last recorded phase onto the carrier clock signal in first bit positions, encoding a phase change of the second client clock signal from a last recorded phase onto the carrier clock signal in second bit positions different from the first bit positions, and transmitting the carrier clock signal with the encoded phases of the first client clock signal and the second client clock signal over a single wire from the first integrated circuit to a second integrated circuit.
