US Patent 7515614 Source synchronous link with clock recovery and bit skew alignment

A high speed transmission system transfers data streams over a set of data links. Each data link may carry a number of bit streams. A clock signal is not transmitted over the optical link. Instead, an indication of the appropriate clock signal frequency and please is embedded in the transmitted data. At the receiving end, a clock signal of an appropriate frequency and phase is generated. The new clock signal is used to sample and reconstruct the original data streams.
