Tests for the Readout Chain components of the CBM STS

The physics goals of the CBM experiment require very high interaction rates that can be exploited with fast and radiation hard detectors equipped with self-triggering electronics. The STS is the essential tracking detector of the CBM experiment and it poses very demanding requirements in term of bandwith and channel density. The front-end board (FEB) with STS-XYTER ASICs and the read-out board (ROB) with GBTX and Versatile Link components are main elements of the STS readout chain. Several tests have been carried out to check their performance, system integration and functionalities. This contribution will present an overview about devices, tests, experimental setup and results.
