8. I/O Setup/Hold Plateau Derating
9. I/O Delta Rise/Fall Rate(1/slew-rate) Derating
10. This parameter is fir system simulation purpose. It is guranteed by design.
11. For each of the terms, if not already an integer, round to the next highest integer. tCK is actual to the system clock cyc le time.
<Reference>
The following table specifies derating values for the specifications listed if the single-ended clock skew rate is less than 1.0V/ns.
This derating table is used to increase tDS/tDH in the case where the input level is flat below VREF 310mV for a duration of
This derating table is used to increase t
up to 2ns.
is calated as 1/SlewRate1-1/SlewRate2. For example, if slew rate 1 = 5V/ns and slew rate 2 =.4V/ns then the Delta Rise/Fall
Rate =-0/5ns/V. Input S/H slew rate based on larger of AC-AC delta rise/fall rate and DC-DC delta rise/fall rate.
