The LUCID Trigger Board is a state-of-the-art VME 9U compatible unit designed to support high-speed data transmission and trigger processing in high-energy physics experiments. This system features multiple LVDS signal buffers and FPGA-based processing units, capable of fulfilling luminosity group requests to ROS at a speed of 160 MB/s. Key components include two detectors with ~200 Bytes/event and a controlled logic interface for real-time trigger operations. With support for various input configurations, this unit optimizes data collection and processing efficiency for complex experiments.
