Abstract
A phase/frequency detector (18) includes a first memory circuit (50), a second memory circuit (52), a first set circuit (54), a second set circuit (58) and a reset circuit (56). The first memory circuit (50) provides a first output signal (20) in response to the first input signal (12). The second memory circuit (52) provides a second output signal (22) in response to the second input signal (14). The first set circuit (54) initiates the transition of the first memory circuit (50) to the active state, and the second set circuit (58) initiates the transition of the second memory circuit (52) to the active state. The reset circuit (56) initiates the transition of the memory circuits (50, 52) to the inactive state.
