WebDec 3, 2024 · The design has a uart receiver module. The received byte will be pushed to the recv FIFO. This part must be clocked by a high frequency clock such as 250 MHz to sample 50 mbps uart bit at least 5 times, which is OK in practice. ... I also used a synchronizer module at the input of the uart receiver module to avoid metastability … Figure 12 Timing for handshake synchronizer. Asynchronous FIFO synchronization. FIFO is best way to synchronize continuously changing vector data between two asynchronous clock domains. Asynchronous FIFO synchronizer offers solution for transferring vector signal across clock domain without risking metastability and coherency problems. Webpointer of a six-layer-deep FIFO to count from zero to five and loop back to address zero. A Gray encoder targeting counting from zero to seven for a full 3-bit counter will fail when the pointer moves from five to zero (Figure 5). Designing a Gray encoder may give a false sense of secu-rity if you fail to account for these details. Both junior and fh07
