Test of the STS-XYTER2 frontend ASIC for the CBM Silicon Tracking System — •Adrian Rodriguez Rodriguez^1,2 and Jörg Lehnert² for the CBM collaboration — ¹Goethe Universität Frankfurt am Main — ²GSI Helmholtzzentrum für Schwerionenforschung

The Silicon Tracking System (STS) is the essential tracking component of the CBM experiment. The STS-XYTER2 is the prototype ASIC dedicated for reading out the double-sided sensors of the STS. It is a low power, self-triggering ASIC which generates timing and energy information for each sensor signal. After tests of the previous prototype, the chip design was revised. The current ASIC version implements various improvements to achieve the desired noise levels, and ensure fail-safe operation. The digital backend was completely re-designed. A new readout protocol was developed and implemented for operation with the GBTx data concentrator. Several tests are carried out to check chip functionalities, performance, and system integration aspects. An overview of the experimental setup, device tests and results will be presented.
