US Patent 7426632 Clock distribution for interconnect structures

Some embodiments of the invention include an interconnect structure having a plurality of connector circuits to transfer messages among a number of devices. Each of the connector circuits includes a data transfer unit to transfer messages and a clock unit to provide timing to transfer the messages. The interconnect structure propagates a master clock signal serially through the clock units of the connector circuits to generate a number of different input clock signals. The timing provided by each of the clock units is based on the timing of one of the input clock signals. Other embodiments are described and claimed.
