AC CHARACTERISTICS
(AC opterating conditions unless otherwise noted)
Note:
TM Technology Inc. reserves the right
to change products or specifications without notice.
CLK cycle time
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
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.
1. Parameters depend on programmed CAS latency.
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.
