WebDeterministic latency uncertainty (DLU) is the LMFC skew in the JESD204B system and is determined by the difference between the earliest and latest possible capture of SYSREF in the system. Figure 1 illustrates the worst case DLU that occurs when setup and hold time requirements for SYSREF capture are not met at every device in the system. This WebThe JESD204B controller IP is a highly optimized and silicon agnostic implementation of the JEDEC JESD204B.01 serial interface standard targeting both ASICs and FPGAs. The …
