White Rabbit is an extension to Ethernet network with sub-nanosecond
accurate synchronization and gigabit rate data transfer speed. You can
find more information on White Rabbit technology and use-cases on:
The Starting Kit has been designed to test and check if the White
Rabbit technology meets your requirements and also to ease the
understanding on what one can do with it and how to integrate it in your
own project. It is the easiest way to get aquainted with White Rabbit
The starting kit uses two SPEC
and fmc-dio-5chttla FMC 5-channel Digital I/O
module cards also
called nodes in the White Rabbit world. Each node makes basic
operations such as input timestamping or programmable output pulse
Additionally, specific software and gateware layers allow to use it as a
standard network interface card implementing the White Rabbit
Network packets with accurate time-stamping information are generated
and timestamped at the hardware level to achieve the highest accuracy.
The White Rabbit Starting Kit is based on different projects:
spec-sw:: driver to
communicate to the card through PCIe and a set of tools to
wr-nic:: gateware that
includes the NIC & DIO capabilities.
wrpc-sw: white rabbit PTP
firmware for the synchronization.
You can buy the SPEC and
fmc-dio-5chttla FMC 5-channel Digital I/O
from different vendors. You also need different cables to repeat the
experiments described in the White Rabbit Starting Kit manual. For your
convenience you can also buy a complete kit that includes everything you
Starting project to update gateware and software to latest releases of Linux (16.04/18.04, currently work only up to 14.04.) and WRPC 4.2.
Scheduled for Q4 of 2019 a project to add two new features: 1) Local generation of output pulse of configurable width at configurable frequency, 2.-Local generation of interrupts at a configurable frequency (we need 1kHz) that are timestamped
