The CMS Barrel Calorimeter Processor near production (BCP V2) board evaluation

Abstract The Barrel Calorimeter Processor (BCP), based on ATCA blade architecture, has been developed for the readout of the electromagnetic calorimeter (ECAL) and hadron calorimeter (HCAL) subdetectors of the CMS experiment. The BCP supports 120 optical receive channels of up to 25 Gbps, 72 optical transmit channels of up to 25 Gbps, an AMD XCVU13P UltraScale+ FPGA, and an embedded AMD Zynq UltraScale+ SoC. The near production BCP V2 is currently undergoing testing. This presentation highlights key testing results, such as high-speed link performance, power integrity, thermal performance and clock phase alignment as well as lessons for the design of the upcoming production BCP V3.
