Abstract
A lock detector (16) includes a set circuit (64), a reset circuit (120), and a latch circuit (80). The latch circuit (80) provides an output signal (82) in response to the temporal relationship of the first input signal (12) and the second input signal (14). The set circuit (64) initiates the transition of the latch circuit (80) to the locked state, while the reset circuit (120) initiates the transition of the latch circuit (80) to the not-locked state.
