Abstract
A delay lock loop (DLL) circuit, and an associated method, for a receiver. The delay lock loop circuit is selectably operable in an acquisition mode and a tracking mode. A selector selects operating parameters of elements of the delay lock loop circuit to cause operation of the circuit alternately in the acquisition mode and the tracking mode. Through appropriate selection of the operating parameters, a selected one of the operating modes is effectuated. The delay lock loop circuit is amplitude-independent, operable irrespective of the values of the input signals applied thereto.
