ID Parameter Symbol CK = 533 MHz Unit
Min Max
LP17 DQ and DQM setup time to DQS
(differential strobe)
tDS 280 — ps
LP18 DQ and DQM hold time to DQS
(differential strobe)
tDH 220 — ps
LP21 DQS latching rising transitions to
associated clock edges
tDQSS 0.75 1.25 tCK (avg)
LP22 DQS high level width tDQSH 0.4 — tCK (avg)
LP23 DQS low level width tDQSL 0.4 — tCK (avg)
NOTE
To receive the reported setup and hold values, write calibration
should be performed in order to locate the DQS in the middle of
DQ window.
NOTE
All measurements are in reference to Vref level.
NOTE
Measurements were done using balanced load and 25 ohms
resistor from outputs to VDD_REF.
