The LDS SATA 3 HOST XK7U IP incorporates the Transport layer, the Link layer and the PHY layer on a Xilinx Kintex 7 Ultrascale speed grade 2 FPGA. The LDS SATA 3 HOST XK7U IP is compliant with Serial ATA III specification and signaling rate is fixed to 6Gbs. The LDS SATA3 HOST XK7U IP is fully synchronous with system frequency (Clock_sys) at 37.5MHz in case of 1.5Gbs speed selection, at 75MHz in case of 3Gbs speed selection and 150MHz in case of 6Gbs speed selection. The source code format is available for ease of customization. The customization can be done by Logic Design Solutions and DO254 documentation is available on request.
