NOTE
SDRAM CLK and DQS-related parameters are measured from the 50%
point—that is, “high” is defined as 50% of signal value and “l(fā)ow” is defined
as 50% of signal value. DDR SDRAM CLK parameters are measured at the
crossing point of SDCLK and SDCLK (inverted clock).
Test conditions are: Capacitance 15 pF for DDR PADS. Recommended
drive strength is Medium for SDCLK and High for Address and controls.
