- Abstract
- The present invention relates to a system and an apparatus for synchronization between heterogeneous periodic clock domains, a synchronization failure detecting circuit, and a data receiving method. The synchronization system between heterogeneous periodic clock domains including a sender and a receiver operated according to heterogeneous periodic first clock and second clock, respectively, includes: a sender that outputs a prediction clock obtained by delaying the first clock for a first time; and a receiver that predicts success and failure of synchronization between the first clock and the second clock by using the prediction clock and selectively delays the second clock for a second time according to the predicted results to synchronize the second clock with the first clock.
