Synchronous input signal capture system

摘要

A synchronous digital signal capture system includes a first flip-flop and a synchronization module. The first flip-flop receives a logic control signal and a first clock signal having a first frequency. The first flip-flop is configured to output a synchronized data signal based on the logic control, and generate a synchronous reset signal that is a logic inverse of the synchronized data signal generated at the data output. The synchronization module receives a primary data signal and is configured to generate the logic control signal based on the primary input signal, a second clock signal, and the synchronous reset signal such that the first flip-flop generates the synchronized signal.
