17 N310/N300 Ethernet-Based Synchronization White Rabbit ni.com

Ethernet Synchronization Requirements Meet synchronization and timing requirements for cellular and other time sensitive applications Alternative to 10 MHz / PPS

18 Ethernet Synchronization Requirements Meet synchronization and timing requirements for cellular and other time sensitive applications Alternative to 10 MHz / PPS and GPS based approaches Suitable for indoor environments and areas with limited GPS coverage Multiple km cable lengths Suitable for a broad range of user applications

19 Ethernet Synchronization - What is White Rabbit? Extension of IEEE1588 Precision Time Protocol (PTP) standard Physical layer clock synchronization (similar to SyncE) Enhancement of IEEE timestamps using phase detection Automatic evaluation and compensation of link asymmetry Currently undergoing standardization by IEEE P1588 Working Group as a High Accuracy PTP Profile (WRPTP) Expected IEEE standard publication in 2018 or 2019 PTP messages used by White Rabbit

20 Ethernet Synchronization - Why White Rabbit? Open specification, open hardware, open software Developed through global academic and industry collaboration Partners include CERN, GSI Helmhotz Centre for Heavy Ion Research, and universities around the world Broad applicability of Ethernet (cellular, scientific, academic, etc.) Scalable to thousands of nodes
