    GDDR6 Controller IP

    OverviewFeaturesRequest Datasheet

    GDDR6 interface provides full support for the GDDR6 interface, compatible with standard JESD250, JESD250A and JESD250B specification with version 3.11 and DFI-version 4.0 or 5.0 Specification Compliant. Through its GDDR6 compatibility, it provides a simple interface to a wide range of lowcost devices. GDDR6 Controller IP is proven in FPGA environment. The host interface of the GDDR6 can be simple interface or can be AMBA AHB, AMBA AHBLite, AMBA APB, AMBA AXI, AMBA AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol.
