output delay
Output data
hold time
CLK high pulse width
CLK low pulse width
Input setup time
Input hold time
CLK to output in Low-Z
CLK to output
in Hi-Z
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf) = 1ns.
If tr & tf is longer than 1ns, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]ns should be added to the parameter.
