Abstract

The present disclosure provides a metastability detector (60) and a calibration method for ensuring synchronous data transfer in distributed synchronous systems (10). By providing a metastability detector (60) that integrates hardware adapted to, for reference signal patterns sent from first transceiver device to a second transceiver device, determine a metastability value based on deviations from the 50% duty cycle, and by providing a calibration method that adjust clock phases of generated signal patterns based on metastability values determined by measuring deviations from the 50% duty cycle, embodiments of the present disclosure can ensure reliable, high-speed data transfer with minimal synchronization issues in distributed synchronous systems (10). The approach may further account for variations over time and because of operating conditions, thereby maintaining optimal performance of data transfer in distributed synchronous systems (10).
