Development of a Readout Link Board for theTileCal Phase 2 Demonstrator

The ATLAS Tile Calorimeter phase 2 upgrade demonstrator aims at installing a hybrid on-detector electronic system replacing 1-4 adjacent TileCal drawers in ATLAS starting end of phase 0, combining a fully functional phase 2 system with circuitry making it compatible with the present system. We are reporting a second generation prototype link and controller board connecting the drawer to off-detector electronics in USA-15. The new boards main logic component is a XILINX Kintex7 FPGA connected to an 12x5 Gb/s AVAGO opto transmitter and a 4x10 Gb/s QSFP+ connector. One of the latter will be chosen for the final design
