Digitizer module multi-channel agregator was created to paralelize high amount of digitalizaton modules (Fast ADC modules). The device is designed to be connected to chain which handles the data from/to the digitalizaton modules. Internal FPGA communicates with the ancestor through upward bi-directional bus and propagates data to the descendant through downward bus. The most upper module is conneted to USB interface which sends data to computer. High data throughput, low latency and data arbitration are advantages of the device.
