Abstract
An integrated circuit comprises a frequency detector. The frequency detector comprises a timer state machine unit operably couplable to a timer and arranged to receive an incoming carrier signal; determine whether the incoming carrier signal comprises a valid frequency; generate a valid carrier indication when the incoming carrier signal is determined as having a valid frequency; and adjust the timer between at least a first timing mode of operation and a second timing mode of operation of the frequency detector in response to the determination.
