DQ Slew Rate
DDR24 DQS - DQ Skew (defines the Data valid window in read cycles related to DQS)
DDR25 DQS DQ in HOLD time from DQS
DDR26 DQS output access time from SDCLK posedge
All units in ‘ps’.
Test conditions are at capacitance=15pF for DDR PADS. Recommended drive strengths are medium for SDCLK and high for
address and controls.
SDRAM CLK and DQS related parameters are measured from the 50% point. That is, high is defined as 50% of the signal
value, and low is defined as 50% of the signal value. DDR SDRAM CLK parameters are measured at the crossing point of
SDCLK and SDCLK (inverted clock).
Test conditions are at capacitance=15 pF for DDR PADS. Recommended drive strengths are medium for SDCLK and high for
address and controls.
