Method and arrangement for recovering a clock signal from a data signal

A method and an arrangement are disclosed for recovering a clock signal from a data signal. At least a first portion of the data signal is synchronized in a decision circuit with a clock signal from a controlled oscillator. The phase difference between the synchronized signal and at least a second p...

Zusammenfassung:A method and an arrangement are disclosed for recovering a clock signal from a data signal. At least a first portion of the data signal is synchronized in a decision circuit with a clock signal from a controlled oscillator. The phase difference between the synchronized signal and at least a second portion of the data signal, which is not fed to the decision circuit, is determined by means of a phase detector and used to control the clock signal of the controlled oscillator, with the synchronized data signal and the portion of the data signal not fed to the decision circuit being applied to the phase detector bit-synchronously.
