    摘要: A phase detector and corresponding method. The phase detector detects a transition of a first signal and generates an output signal having a first value if a transition of a second signal occurs before the transition of the first signal and having a second value if the transition of the second signal occurs after the transition of the first signal. The output signal is maintained at the generated value until another transition of the first signal is detected. A strobe signal may be used to strobe the output signal.
