JEDEC JESD204B is the third revision of the JESD204 high-speed serial digital interface specification for data converters and logic devices. This specification supports multiple data lanes and lane synchronization, making it suitable for use in modern 3G, 3G+ and 4G broadband wireless communications.
The document introduces the JEDEC JESD204B specification, the third‑generation high‑speed serial interface for data converters. It describes the evolution from JESD204 (2006) through JESD204A (2008) to JESD204B, highlighting new features such as higher lane rates, deterministic latency, and harmonic clocking.
Key benefits discussed include simplified PCB layout, reduced pin count, higher system performance, and compatibility with existing 8B/10B PHYs. The paper also outlines device subclasses, clocking schemes, and provides an extensive list of abbreviations and references for further study.
