Platform Architecture

The Xilinx UltraScale+ VU9P-3 FPGA is directly connected to 48 x SFP28 and 4 x QSFP28 front panel ports, providing a platform to

support existing Arista applications such as Low Latency Mux or High Precision Timestamping, while allowing the FPGA to be also

utilized by the customers for their custom applications. The FPGA also has three direct connections to the CPU card and four direct

connections to 8G DDR4 memory.
