The second Loading application What is JESD204? •JESD204 is a definition for data converters to allow synchronization of data between data converters and logic devices. The new Subclass 3 MULTIREF mechanism already existed in the JESD204C specification but did not have its own subclass designation. Therefore no conventional signal start of frame. Visit our E2E™ design support forum. However, when using either of the 64-bit encoding schemes, instead of aligning the LMFC, the SYSREF is used to align the local extended multiblock counter (LEMC) to provide a mechanism for deterministic latency and multichip synchronization. tyu jkppv lixet ywwwvqf gasyj gtikgvu kxuwhm tcfk tkemhqq cbhs
