Using an external clock and time reference source, such as the CDA-2990 accessory, offers a precise and convenient method of baseband synchronization for high channel count systems where devices are located near each other, such as in a rackmount configuration.
Therefore, indoor, urban, or hostile environments restrict the use of GPSDO.
Ethernet-based synchronization enables precise baseband synchronization over large distances in GPS-denied environments.
White Rabbit is a fully deterministic Ethernet-based network protocol for general purpose data transfer and synchronization.
This project is supported by a collaboration of academic and industry experts such as CERN and GSI Helmholtz Centre for Heavy Ion Research.
White Rabbit is an extension of the IEEE 1588 Precision Time Protocol (PTP) standard, which distributes time references over Ethernet networks.
