Abstract	In the Phase-I upgrade of ATLAS experiment and the Single-Phase ProtoDUNE (Prototype for the Deep Underground Neutrino Experiment) experiment, a PCIe based FELIX (Front-End LInk eXchange) system has been deployed for data acquisition, to interface the front-end electronics. As the only custom hardware in the FELIX system, the Gen3 PCIe card is also adopted by other experiments for instance sPHENIX and CBM experiments. The same PCIe based architecture will be used in the ATLAS HL-LHC (High Luminosity Large Hadron Collider) upgrade, and the DUNE experiment. A new generation card has been developed to support 25+ Gbps high speed fiber optical links and 16-lane Gen4 PCIe bus. There is also an on-board DDR4 module to buffer the event data for DUNE experiment. With this card as a demonstrator, all important functions have been evaluated. The hardware design and the test results will be discussed in this paper.
