摘要
A phase-detector circuit is disclosed. The phase-detector circuit comprises a plurality of phase comparators which detects a phase difference between receipt data and a clock signal of a plurality of clock signals having the same frequency and phase difference of a predetermined angle with each other, and generates and outputs signals for up/down signals for synchronizing a phase. The phase comparator generates and outputs a signal for the up/down signals having a pulse width including a detected phase-time difference and a predetermined delay time.
