When a design moves from 16- to 8-bits, the clock frequency has to be doubled. But since the XIO1100 offers DDR clocking, the frequency can be kept steady at 125-MHz. With 250-MHz-based FPGAs designs, an extra clock buffer is required.

WebJan 1, 2024 · implement a robust design for the topologies that TI supports. At this time, TI does not provide timing parameters for the processor ’s DDR PHY interface. It is still expected that the PCB design work (design, layout, and fabrication) be performed and reviewed by a highly knowledgeable high-speed PCB designer.

WebThe PHY also configures and controls all leveling and training functionality. The PHY must also be programmed according to a design’s DRAM timing parameters; most of these values can be found in the memory vendor’s spreadsheet. TI’s Keystone 2 DDR3 Register Calculation Spreadsheet can also be used to help populate the DDR3 PHY registers.
