White Rabbit
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.
White Rabbit Switch - Software
WR Switch firmware v7.0 release
Dear Rabbits,
Following the months of preparation, the WRS firmware v7.0 is now released!
We would like to invite you to download, validate it in your installations and ultimately update your switches with it.
White Rabbit core collection
White Rabbit PTP Core v5.0 released
We have just released v5.0 of the WR PTP Core. You can find more details and all the links to download the demo binaries and documentation on our release wiki page
HiCCE-FMC-128
The Second prototype was tested.
We successfully tested the HiCCE-FMC-128 version 2 using a commercial low-cost FMC carrier, Avnet ZedBoard.
1-to-8 Pulse and Frequency Distribution Amplifier
2019-06 Aivon produces S/N 20 and beyond
As of June 2019 more than 20 pcs of the FDA/PDA design have been produced. So far the design is stable and performance has been sufficient for many users.

24-01-2019: WR Job vacancy at Besancon Observatory
A 1-year postdoctoral position is available at the Besancon Observatory
(France, 47.241499034N 5.987162718E) on time transfer.
While the original interest lies in using GNSS for time transfer,
including security aspects of GNSS spoofing and multi-constellation data
fusion, we wish to extend the work on White Rabbit time transfer from a
user perspective.
Indeed, a WR network spanning from the FEMTO-ST Time & Frequency
department to the Besancon
Observatory
and teaching department of the university is operational and is now to
be used for distributed signal generation and radiofrequency signal
acquisition. Thus, the work would focus on using existing White Rabbit
enabled ADC hardware, WR-synchronized DDS and data transfer.
WRS Fan-less hardware
Low Jitter Performance of WRS-FL
The performance of WRS-FL-LJ, a special version of WRS-FL[1] with
low-jitter circuits support, has been tested.
Comparing to standard WRS-FL, the WRS-FL-LJ includes two major
improvements:
1: adding a extra AD9516 for 10MHz clock input
2: replacing the TCVCXO VM53S with a better TCVCXO or OCXO (
T604-025.0M[2] used in this test).
