ABSTRACT:
Apparatus and methods for setting wakeup times in a communication device are disclosed where setting the wakeup times includes estimating the lock on time of a frequency synthesizer in order to minimize the wakeup time and extend sleep times for maximal energy savings. A disclosed apparatus includes an estimator to receive a current lock on time of a frequency synthesizer, which is the time taken by the frequency synthesizer to lock on to particular frequency after a wakeup signal has been issued to turn on the synthesizer after a sleep period. The estimator calculates a latest estimated lock on time based at least on the current lock on time of the frequency synthesizer and determines an enable signal timing information based on the estimated lock on time. The apparatus also includes a timer configured to receive the enable signal timing information and issue at least one enable signal to turn on other circuitry in the transceiver after the synthesizer lock on period based thereon. Corresponding methods are also disclosed.
