Notes to
(1) There is one leveling delay chain per I/O sub-bank (for example, I/O sub-banks 1A, 1B, and 1C). You can only have one memory interface in each

The –90° write clock of the ALTMEMPHY megafunction feeds the write-leveling
circuitry to produce the clock to generate the DQS and DQ signals. During
initialization, the ALTMEMPHY megafunction picks the correct write-leveled clock
for the DQS and DQ clocks for each DQS/DQ group after sweeping all the available
clocks in the write calibration process. The DQ clock output is –90° phase-shifted
compared to the DQS clock output.
Similarly, the resynchronization clock feeds the read-leveling circuitry to produce the
optimal resynchronization and postamble clock for each DQS/DQ group in the
calibration process. The resynchronization and postamble clocks can use different
clock outputs from the leveling circuitry. The output from the read-leveling circuitry
can also generate the half-rate resynchronization clock that goes to the FPGA fabric.
