The VCK190 XCVC1902 ACAP DDR interface performance is documented in the Versal AI Core Series Data Sheet: DC and AC Switching Characteristics (DS957). The VCK190 DDR4 DIMM interface adheres to the constraints guidelines documented in the PCB guidelines for DDR4 section of the Versal ACAP PCB Design User Guide (UG863). The DDR4 DIMM interface is a 40Ω impedance implementation. Other memory interface details are also available in the Versal ACAP Memory Resources Architecture Manual (AM007). For more details, see the Micron MTA9ADF1G72AZ-3GE1 data sheet at the Micron website. The ACAP connections for the feature described in this section are documented in the VCK190 board XDC file, referenced in Xilinx Design Constraints.
