Title: SCA controller for the ATLAS calorimeter

Abstract

The front-end readout of the ATLAS liquid argon calorimeter will store data locally in analog pipeline memories at the LHC beam crossing frequency of 40 MHz. Switched capacitor array chips meeting the ATLAS readout requirements will be used. These new chips axe capable of simultaneous read and write operations, and allow random access to storage locations. To utilize these essential design features requires a substantial amount of fast control and address bookkeeping logic. We have designed a controller capable of operating the pipelines as analog random access memories and that satisfies the ATLAS readout requirements. The pipeline controller manages the data of 144 time samples and can operate at a mean trigger rate of about 75 kHz, when reading out five time samples per event. We are currently prototyping an integrated version of the controller implemented in a FPGA from Xilinx.
