This paper describes a fast serial digital signal receiver for applications in nuclear instrumentation. The proposed design uses Microsemi Polarfire FPGA embedded Ethernet transceiver data oversampling (with frequency up to 12.7 GHz) and deserialization. subsequent implemented processing chain then analyses the oversampled array (at least 4 samples per bit are required by logic). begins with frame buffer, which ensures that entire sampled can be captured 5-bit majority parallel filter....
