The next generation of frontend readout at COMPASS-II — •Tobias Grussenmeyer, Maximilian Büchele, Horst Fischer, Matthias Gorzellik, Florian Herrmann, Philipp Jörg, Kay Königsmann, Paul Kremser, and Sebastian Schopferer — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

The GANDALF framework, a high precision, high performance detector readout system, capable of highspeed pulse and logic signal digitization, has been extended by a new mezzanine card with optical connectors. Using the GTP transceivers of the Spartan-6 SLX45T on the mezzanine card in a special configuration allows high speed data transmission to frontend electronics with fixed latency. In the reverse direction, measured data is transmitted at the maximum speed of 3 GBit/s.

At the COMPASS-II experiment at CERN SPS this will be used for the TDC frontend readout of new driftchambers and RICH Thick-GEM detectors.
