Emulation in FPGA of G-Link Chip-set of Tile Calorimeter Electronic System

The ATLAS Tile Calorimeter front-end and the back-end electronics use the Agilent HDMP-1032/1034 Transmitter/Receiver chip-set as physical layer. In the back-end is implemented the G-link receiver, the HDMP-1034, which is used to receive and de-serialize the data sent by a G-Link transmitter, the HDMP-1032 in the front-end. The emulation of their functionality, in a FPGA, was required to be used in a TileCal front-end electronics tester, called MobiDICK4, implemented at CERN, with future utilization planned for the upgrade of the TileCal electronic system. We have implemented the emulation of the functionality of this chip-set in a Xilinx ML605 board equipped with a Virtex-6 FPGA, around the high-speed serial GTX transceivers embedded in that FPGA. A description of the functionality and the CIMT coding scheme used by this chip-set will be presented. Also, the implementation of our design in the FPGA will be described. Finally, the tests performed, the results and the conclusion about this work will be presented.
