ABSTRACT:
A digital detector circuit for recovering the bit timing of a data stream with a PLL includes a digital phase detector and a digital pulse length detector whose output signals are added and integrated, and the result is used for controlling the oscillator frequency. The output signal of the pulse length detector is determined by a corresponding algorithm, one slow and two fast, with direction-dependent output signals of the pulse length detector being generated.
