The Belle II Silicon Vertex Detector readout chain

The Silicon Vertex Detector of the future Belle II experiment at KEK (Japan) will consist of 6'' double-sided strip sensors. Those are read out by APV25 chips (originally developed for CMS) which are powered by DC/DC converters with low voltages tied to the sensor bias potentials. The signals are transmitted by cable links of about 12 meters. In the back-end, the data are digitized and processed by FADC modules with powerful FPGAs, which are also capable of precisely measuring the hit time of each particle in order to discard off-time background.
