Abstract
Systems and methods related to phase-locked loops circuitry and lock-detect circuitry are provided. Some of the systems and methods allow sharing of lock-detect circuitries between multiple phase-locked loops or other suitable circuitry. Others allow multiple circuitries to select from multiple lock-detect circuitries that may use different lock-detect techniques.
