Command /
Slew Rate
Test conditions are: Capacitance 15 pF for DDR contacts. Recommended drive strengths: Medium for SDCLK and High for
address and controls.
SDCLK and DQS related parameters are measured from the 50% point. For example, a high is defined as 50% of the signal
value and a low is defined as 50% of the signal value. DDR SDRAM CLK parameters are measured at the crossing point of
SDCLK and SDCLK_B
These values are for command/address slew rates of 1 V/ns and SDCLK / SDCLK_B differential slew rate of 2 V/ns. For
different values use the settings shown in
