Abstract
A digital PLL circuit includes a sampler which samples a burst data signal depending on N phase clock signals to produce N phase sampled data signals. Based on the N phase sampled data signals, an edge phase detector detects edge information and a duty detector detects duty information signals in synchronization with the reference signal. A selector selects an optimal sampled data signal from the N phase sampled data signals depending on the edge information and the duty information, and a retiming section retimes the sampled data signal selected in synchronization with the reference signal.
