TIGER/GEMROC is a new scalable readout system developed for the CGEM-IT, a novel cylindrical GEM detector designed to replace the inner drift chamber of the BESIII experiment in its upcoming upgrade. The versatility of the system allows it to read other MPGDs with GEM-like signals and seamlessly interface with the many subsystems of a modern physics experiment. The entire system revolves around the TIGER chip, a new 64-channel mixed-signal ASIC capable of simultaneous charge and time measurements, and GEMROC, an FPGA-based off-detector module controlling the chips and managing the data flow during the acquisition. This paper provides an overview of the system and presents the first preliminary results of a test beam with 80 GeV muons on the H4 line at CERN to validate the performance of the readout chain.
