Abstract
A system and method for effectively supporting a data transmission procedure includes a phase-locked loop with a phase detector that compares a clock signal and input data to generate a phase error signal for adjusting the clock signal that is generated from a voltage-controlled oscillator. The phase detector includes a positive-edge detector circuit that generates an edge detection signal P to indicate whether data transitions are present in the input data. The phase detector also includes a lead/lag indicator circuit that generates a lead/lag indicator signal T to indicate whether the clock signal is early or late with respect to the input data.
