An apparatus for determining phase difference information between a first signal and a second signal includes a first detector, a second detector and a counter. The first detector is used for detecting a first value of the first signal, the second detector is used for detecting a second value of the second signal, and the counter is used for counting a timing when the first signal is at the first value and a timing when the second signal is at the second value with a reference clock signal to generate a counter value which serves as a basis of the phase difference information.
