Abstract
A phase detector is adapted to receive first and second signals and generate third and fourth signals representative of the difference between the phases of the first and second signals. The phase detector assert the third signal in response to the assertion of the first signal and unasserts the third signal in response to the assertion of the second signal. The phase detector asserts the fourth signal in response to the assertion of the third signal and unasserts the fourth signal in response to unassertion of the first signal. The phase detector may include combinatorial logic gates, thereby to generate the third and fourth signals in response to logic levels of the first and second signals. The phase detector may include sequential logic gates, thereby to generate the third and fourth signals in response to transitions of the first and second signals.
