Abstract: The invention relates to an improved backplane communication system. In one embodiment this is accomplished by a central data processing card including at least one master central card and a plurality of slave central card, wherein each master central card and the slave central card having a first SerDes (serializer-deserializer), a first clock and a first faster local clock, a line card including a second SerDes (serializer-deserializer), a clock selection module and a second faster local clock and a serial communication channel coupling the central data processing card and the line card, wherein the master central card uses the first faster local clock to transmits the data at a rate higher than actually required, wherein the transmitted data includes a stuff data to adjust to the link data rate between the central data processing card and line card.
