AC CHARACTERISTICS

(AC operating conditions unless otherwise noted)

Refer to the individual component, not the whole module.

Parameter Symbol Min Max Unit Note

CLK cycle time t

7.5 1000 ns ns

CLK to valid output delay t

SAC

5.4 ns 1, 2

Output data hold time t

3.0 ns 2

CLK high pulse width t

2.5 ns 3

CLK low pulse width t

2.5 ns 3

Input setup time t

1.5 ns 3

Input hold time t

0.8 ns 3

CLK to output in Low-Z t

SLZ

1 ns 2

CLK to output in Hi-Z t

SHZ

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 paremeter.

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.
