Abstract

Clock and data regenerator with demultiplexer function wherein the clock and phase generator operates with four sampling flip-flops whose output signals are compared with one another with the aid of two pairs of EXOR elements. The associated phase signals generated by the EXOR elements are added and compared with one another. The phase regulating voltage thus obtained controls an oscillator which generates the sampling clock signals.
