SYSTEM AND APPARATUS FOR SYNCHRONIZATION BETWEEN HETEROGENEOUS PERIODIC CLOCK DOMAINS, CIRCUIT FOR DETECTING SYNCHRONIZATION FAILURE AND DATA RECEIVING METHOD

摘要

PURPOSE: A system and apparatus for synchronization between heterogeneous periodic clock domains, a circuit for detecting synchronization failure and data receiving method are provided to avoid synchronization failure without latency by estimating the synchronization failure between heterogeneous periodic clock domains. CONSTITUTION: A sender(100) outputs a prediction clock having a first clock which is delayed a first time. A receiver(200) predicts the synchronization failure between the first clock and a second clock by using the prediction clock. The receiver delays the second clock which is selected from an estimation result by a second time to synchronize the second clock with the first clock. The sender detects the synchronization failure between the estimation clock and the second clock, thereby estimating synchronization failure generation time in advance.
