Abstract:
1. A phase detector, comprising: a first sampling unit, arranged for sampling a first data input signal to generate a first data signal according to a first clock signal; a second sampling unit, arranged for sampling a second data input signal to generate a second data signal according to a second clock signal; a third sampling unit, coupled to the second sampling unit, arranged for sampling the second data signal to generate a third data signal according to the first clock signal; a fourth sampling unit, coupled to the first sampling unit, for sampling the first data signal to generate a fourth data signal according to the second clock signal; a first phase determining module, coupled to the first sampling unit and the third sampling unit, arranged for generating a first phase detecting result according to the first data signal and the third data signal; and a second phase determining module, coupled to the second sampling unit and the fourth sampling unit, arranged for generating a second phase detecting result according to the second data signal and the fourth data signal.
