White Rabbit
White Rabbit provides sub-nanosecond accuracy and picoseconds
precision of synchronization for large distributed systems. It also
allows for deterministic and reliable data delivery.
White Rabbit allows you to precision time-tag measured data and lets
you trigger data taking in large installations while at the same time
using the same network to transmit data.
- sub-nanosecond synchronization
- connecting thousands of nodes
- typical distances of 10 km between nodes
- Ethernet-based gigabit rate reliable data transfer
- fully open hardware, firmware and software
- multi-vendor commercially produced hardware

Job vacancy at CERN to work on White Rabbit and RF
We have an open position at CERN to work for 2-3 years on the evolution of the eRTM board. It is a WR node whose jitter (integrated between 100Hz and 20MHz) is less than 100 femtoseconds, the most precise WR node I know of, originally designed by Mattia Rizzi and Tomasz Włostowski.
