Patent Number Title Of Patent Date Issued
8036333 Clock and data recovery circuit and method of recovering clocks and data October 11, 2011
A clock and data recovery circuit that does not use a reference clock and a method of recovering cocks and data, in which the clock and data recovery circuit includes a clock generation unit, a mirror delay unit, a preamble phase detection unit, and a sampling unit. The clock generation
7508245 Lock detector and delay-locked loop having the same March 24, 2009
A lock detector of a delay-locked loop (DLL) includes a lock detection unit and a bias unit. The lock detection unit generates a charge control signal based on a reference current received from an external source and a plurality of delay signals received from an external voltage-controll
7400182 Clock generator with one pole and method for generating a clock July 15, 2008
A clock generator based on a phase-locked loop with one pole and an improved period jitter characteristic is disclosed. The clock generator comprises a phase detector for generating a phase detection signal and a phase error signal, a charge pump for generating a loop control voltage,
7116145 Phase-locked loop circuit having phase lock detection function and method for detecting phase lo October 3, 2006
A phase-locked loop circuit including a lock detection function is disclosed. The phase-locked loop circuit comprises a lock detection circuit. The lock detection circuit includes a lock-detection-start-signal generator, a lock-detection-clock generator, and a lock-detection-signal g
7084682 Delay-locked loop circuit and method thereof for generating a clock signal August 1, 2006
A delay-locked loop circuit includes a phase frequency detector, a charge pump, a loop filter, a voltage controlled delay line and a coarse lock detector. The phase frequency detector generates an up signal and a down signal corresponding to phase and frequency differences between an inp
