Kintex UltraScale+ FPGAs Data Sheet: DC and AC Switching Characteristics
Table 26 provides the maximum data rates for applicable memory standards using the Kintex UltraScale+
FPGA memory PHY. Refer to Memory Interfaces for the complete list of memory interface standards
supported and detailed specifications. The final performance of the memory interface is determined
through a complete design implemented in the Vivado Design Suite, following guidelines in the UltraScale
Architecture PCB Design Guide (UG583), electrical analysis, and characterization of the system.
