128 Channel 14 bit 125 MS/s Open FPGA Digitizer


The R5560SE is a 3U, 19″ rack-mount 128 Channels 14-bit 125MS/s Open FPGA Digitizer with Single-Ended inputs, designed to attain programmable data processing capabilities.

The R5560SE is designed for the readout of large arrays of detectors (PMTs, segmented HPGe, 3He tubes, …) using a customizable platform and an advanced programmable front-end. . In fact, it is possible to take advantage of the powerful SoC mounted onboard to write a custom pulse processing algorithm on the open FPGA as well as build a middleware/software that fits the needs of the application of interest. Moreover, the advanced Front-End allows to easily connect and manage most of the detectors commonly used in Physics Experiments.

The board can manage simultaneously a large number of digital (LVDS, NIM, TTL) and analog signals, allowing to  implement many functionalities required by physics experiments: signal digitization, complex trigger logic, Pulse Height Analysis with MCA capabilities, Time Tagging, Pulse Shape Discrimination, etc.

It is an optimal solution for large experiments, usually requiring fast digitization of analog signals and usage of several digital lines to interface with external systems. The board  supports multi-board synchronization through a single CAT5e cable, with the possibility scale up to thousands of channels Moreover, the rackmount form factor simplifies the experimental setup in case of multi-board systems, where an effective space management is often a constraint.

SCI-Compiler software, the CAEN block-diagram-based firmware generator and compiler, helps in programming the FPGA to develop intensive real-time data processing .

A free and open-source demo readout software is available to manage the standard pulse height analysis firmware implementing energy measurements using a trapezoidal filter.
