Low power electronics for a submarine neutrinos detector

Two main problems have to be solved in order to realise a km(3) neutrino submarine detector: data flow and power. Both must be limited! Signals from the optical modules cannot be transferred to the shore unaltered. It is necessary to transfer a suitable compressed and codified representation from the optical module to a concentrator. An electronic system triggered by the signal holds analog samples taken at very high frequency (200 MHz). It then successively transforms them into digital code (10 MHz) and applies a first compression algorithm.
