Patent attributes
An apparatus is disclosed for relocking of a locked loop. In an example aspect, the apparatus includes a locked loop, and the locked loop includes a loop and a locked-loop controller that is coupled to the loop. The loop is configured to run responsive to a run signal. The loop includes a memory state component and signal characteristic adjustment circuitry coupled to the memory state component. The signal characteristic adjustment circuitry is configured to produce an output signal having a characteristic that is based on the memory state component. The locked-loop controller is configured to receive an external power mode signal (EPMS). The locked-loop controller is also configured to generate the run signal to have an enable value at a first time when the EPMS is indicative of an external normal mode and at a second time when the EPMS is indicative of an external standby mode.
