OH 3.0 ns 2
CLK high pulse width tCH 2.5 ns 3

Input setup time tSS 1.5 ns 3
Input hold time tSH 0.8 ns 3
CLK to output in Low-Z tSLZ 1 ns 2
CLK to output in Hi-Z tSHZ 5.4 ns
Note:
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.
