Designing a Two-Stage Flip-Flop Synchronizer to Eliminate Metastability in Clock Domain Crossing
Welcome back to our Clock Domain Crossing (CDC) series! In our first post, we introduced the critical challenges of CDC in digital designs. In this article, we focus on one of the most fundamental and effective techniques to tackle metastability, a core issue in CDC: the two-stage flip-flop synchronizer. Understanding metastability and how this simple synchronizer design…
