The GANDALF 6U-VME64x/VXS module has been developed to cope with a variety of readout tasks in nuclear physics experiments and is operated at the COMPASS-II experiment at CERN. Based on this module, a 128-channel Time-to-Digital Converter with a time resolution of 93 ps has been implemented successfully in a Xilinx Virtex-5 FPGA using a shifted clock sampling algorithm. Beyond that, the design was extended by adding scaler channels for simultaneous rate measurements.
