Description
The KM3NeT neutrino telescope will be composed by tens of
thousands of glass
spheres (nodes) including each 31 of small photocathode
(3''). The readout and data
acquisition system of KM3NeT has to collect, treat and send
to shore, in an economic
way, the enormous amount of data produced by the
photomultipliers and at the
same time to provide time synchronization between each
node at the level of 1 ns. It
is described in the present article the integration of the White
Rabbit protocol on the
Central Logic Board (CLB) of the node for synchronizing the
nodes in a transparent
way and the front end ASICs to readout the photomultipliers
and the correspondent
collecting boards. Moreover the Time to Digital Converters
embedded on the CLB
FPGA where the required resolution to measure both, time of
flight ofthe
photomultiplier signals and time stamp of 1 ns are achieved
or the associated
instrumentation are described.
