AC CHARACTERISTICS (AC operating conditions unless otherwise noted)

Refer to the individual component, not the whole module.

Parameter Symbol Value Unit Note

Min Max

CLK cycle time tCC 10 1000 ns 1

CLK to valid output delay tSAC 7 ns 1, 2

Output data hold time tOH 3 ns 2

CLK high pulse width tCH 3.5 ns 3

CLK low pulse width tCL 3.5 ns 3

Input setup time tSS 2.5 ns 3

Input hold time tSH 1.5 ns 3

CLK to output in Low-Z tSLZ 1 ns 2

CLK to output in Hi-Z tSHZ 7 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.
