At a higher data rate, DDR5-4800, the approximate performance increase becomes 1.87X—nearly double the bandwidth as compared to DDR4-3200. WebDuring Write Leveling, CK and DQS are driven by the FPGA while DQ is feedback by the DDR3 SDRAM device to provide feedback.The FPGA then delays DQS using IODELAY taps (Virtex-6 DDR3) or Phaser_OUT taps (7 Series DDR3) until a 0-to-1 transition is detected on DQ.This compensates for DQS/CK skew and ensures the tDQSS specification is met. nail polish peels off
