The VMK180 XCVM1802 device DDR interface performance is documented in the Versal Prime Series Data Sheet: DC and AC Switching Characteristics (DS956). The VMK180 DDR4 DIMM interface adheres to the constraints guidelines documented in the PCB guidelines for DDR4 section of the Versal Adaptive SoC PCB Design User Guide (UG863). The DDR4 DIMM interface is a 40Ω impedance implementation. Other memory interface details are also available in the Versal Adaptive SoC Memory Resources Architecture Manual (AM007). For more details, see the Micron MTA9ADF1G72AZ-3GE1 data sheet at the Micron website. The adaptive SoC connections for the feature described in this section are documented in the VMK180 board XDC file, referenced in Xilinx Design Constraints.
