AC CHARACTERISTICS
Note: 1. Parameters depend on programmed CAS latency.
Elite Semiconductor Memory Technology Inc.
CLK to valid
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
CLK cycle time
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.
