Figure 7–32. Stratix IV IOE Output and Output-Enable Path Registers
Notes to
(1) You can bypass each register block of the output and output-enable paths.
(2) Data coming from the FPGA core are at half the frequency of the memory interface clock frequency in half-rate mode.
(3) The half-rate clock comes from the PLL, while the alignment clock comes from the write-leveling delay chains.
(4) These registers are only used in DDR3 SDRAM interfaces for write-leveling purposes.
(5) The write clock can come from either the PLL or from the write-leveling delay chain. The DQ write clock and DQS write clock have a 90° offset between them.
