Abstract
A phase locked loop (PLL) includes a phase detector, a first low-pass filter, an oscillator, a feedback divider and a cycle slip detector. The cycle slip detector is operable to detect at a first time instance, a cycle slip between an input clock and a feedback clock of the PLL. Upon detection of the cycle slip, the cycle slip detector is operable to increase a loop BW of the PLL. As a result, faster relocking of the PLL is achieved upon occurrence of an abrupt and large frequency difference between the input clock and the feedback clock.
