Patent number: 9419629Abstract: A delay-locked loop (DLL) has a fractional phase frequency (PF) detector that reduces false locking and harmonic locking. The PF detector has a trunk, an upper branch, a lower branch, and a logic module. A delay line provides the PF detector a set of fractional phase-delayed clock signals that are used to prime and/or activate corresponding flip-flops of the trunk, upper branch, and lower branch in a sequence. The use of flip-flops in the lower branch activated by different fractional phase-delayed clock signals avoids false locking and harmonic locking over a wider range of initial delay magnitudes than conventional DLLs.Type: GrantFiled: March 1, 2016Date of Patent: August 16, 2016Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: Gaurav Agrawal, Deependra K.
