Abstract
An upstream multiplexer multiplexes data into first and second serialized data streams based on first and second low frequency clocks each derived from a high frequency clock. A downstream multiplexer multiplexes the first and second serialized data streams into a third serialized data stream based on the high frequency clock. A timing error detector derives an error signal indicative of a phase-misalignment between the high frequency clock and the first and second serialized data bit streams based on the high frequency clock and the first and second low frequency clocks. A phase adjuster adjusts phases of the first and second low frequency clocks relative to the high frequency clock based on the error signal so as to reduce the phase-misalignment.
