126.96.36.199.2. QDR-IV Write Calibration
Write Leveling Calibration
The algorithm optimizes the CK versus DK relationship. It is covered by address and command deskew calibration using the loopback mode.
The algorithm performs per-bit deskew of write data relative to the write strobe and clock. Write deskew calibration does not change dqs_out delays; the write clock is aligned to the CK clock during write leveling.
