Popis:	The CLAS12 experiment is intended to study the generalized parton distributions in exclusive reactions. The CLAS12 Silicon Vertex Tracker must provide the registration of all reaction products at the expected high luminosity. The results of a GEANT4 simulation of the expected physical rates in the SVT are presented. The frequency of the noise hits of the readout electronics is determined on the basis of the capacitive load generated by the attached sensors. In order to find the fraction of the events that are lost due to delays in the readout electronics, a computer simulation of the logic of the data-driven readout FSSR2 chip is performed. At a signal-to-noise ratio of 8 to 1 the readout electronics are capable of processing the expected rates, provided a registration threshold of 0.4 mip is preset.
