Abstract

An unlock detector includes a checker, an accumulator, and a comparator. The accumulator is electrically connected to the checker, and the comparator is electrically connected to the accumulator. The checker includes several checking units. The checker is configured to receive a sampled data signal and a sampled edge signal, and to check the sampled data signal and the sampled edge signal via the checking units to generate several checking results. The accumulator is configured to generate a counting value in a manner of counting according to the checking results. The comparator is configured to compare the counting value with a threshold to generate an unlock-detecting result.
