The digital electronics group of the department for experiment electronics is working on the design (schematics) and after layout and production of the module with the programming of mainly digital electronics in close collaboration with the physics experiment groups at GSI. For these tasks very often Field Programmable Gate Arrays are used on the developed devices, which can fulfil any digital function in parallel and very fast and which can change this function via reprogramming the device. The functions include the analog to digital conversion in external devices, the readout of ASICs and the transport of the data with protocols like Ethernet or custom protocols to minimize the latency. Additionally, very precise time measurements are needed for many detector systems to identify particles. Also for this FPGAs are used, which can be programmed in a very special way to achieve a time difference measurement precision of ~10ps RMS for many channels.
