Folks,
Just to let you know (and I know some of you already know) what was done at CERN regarding high precision timing distribution. Have a look at : http://www.ohwr.org/projects/wr-d3s/wiki
The specs are:
- Frequency range: at least 50 MHz (to be able to distribute 40.079 MHz LHC
bunch crossing frequency)
- Tracking bandwidth: 50 kHz
- Required jitter: < 10 ps rms (10 Hz - 10 MHz)
- Accuracy: < 1ns
- Precision: < 100 ps
There is a demo/proof of concept version:

Please feel free to contact Maciej Lapinski (maciej.lipinski@xxxxxxx) of CERN for more info or clarity in regards to work done and being planned.
