Abstract
Disclosed is a frequency detector. The frequency detector includes a first flip-flop sampling a clock signal based on a data signal to generate a first signal, a second flip-flop sampling a delayed-phase component of the clock signal based on the data signal or sampling the clock signal based on a delayed-phase component of the data signal to generate a second signal, a third flip-flop generating a third signal representing a polarity of a frequency difference between a data rate of the data signal and a frequency of the clock signal based on the first signal and the second signal, and a delay cell generating the delayed-phase component of the clock signal or the delayed-phase component of the data signal. The delayed-phase component has a delay amount set to a value smaller than about 0.25 UI.
