WebAfter reset, the PUB monitors the PHY for basic initialization completion, then automatically executes data training algorithms to calibrate PHY read/write bit de-skew for data eye widening, read/write DQS centering for widest possible data margins, read DQS gating, and DDR3 write leveling delays. WebThe present invention generally provides for adjusting a delay of the read data strobe signal DQS to approximately center the read data strobe signal DQS in the valid data eye window. For example, when the delay is too short, the read data strobe signal DQS is generally earlier than a minimum boundary of the valid data eye window (e.g., trace 140).
WebIntroduction. 1.17.4.2. DQS Enable Calibration. DQS enable calibration ensures reliable capture of the DQ signal without glitches on the DQS line. At this point LFIFO is set to its maximum value to guarantee a reliable read from read capture registers to the core. Read latency is minimized later. Note: The full DQS enable calibration is ...
