A delay locked loop includes an auxiliary phase shifter for controlling a phase blending point after the delay locked loop is initially locked, thereby reducing jitter. A control circuit directs a phase blender to detect the point where two delayed signals are phase-blended, and directs the auxiliary...http://www.google.es/patents/US7583119?utm_source=gb-gplus-sharePatente US7583119 - Delay locked loop having small jitter and jitter reducing method thereof
