See full text

A method and apparatus for performing frequency synthesis in a communication system. A fiber optic repeater connected between a copper bus and a fiber optic cable includes a voltage controlled oscillator and associated circuitry to adjust the frequency at which the repeater operates to match the frequency of the device that generated the incoming data stream. This adjustment is performed on-both data received from the copper bus or the fiber optic cable on a message by message basis.
