Abstract
A phase detection circuit includes a first phase detection path having a first input to receive a first signal, and a second input to receive a second signal. Asynchronous transition detection circuitry detects an early/late relationship between the first signal and the second signal when at least one of the first signal and the second signal transitions from a first state to a second state. Output circuitry generates a control signal with a value based on the early/late relationship.
