Tables 4–98
derivation for different I/O standards on Stratix II GX devices. Examples
are also provided that show how to calculate DCD as a percentage.
Here is an example for calculating the DCD as a percentage for a
non-DDIO output on a row I/O on a -3 device:
If the non-DDIO output I/O standard is SSTL-2 Class II, the maximum
DCD is 95 ps (see
period T is:

Table 4–98. Maximum DCD for Non-DDIO Output on Row I/O Pins
T = 1/ f = 1 / 267 MHz = 3.745 ns = 3,745 ps
(T/2 – DCD) / T = (3,745 ps/2 – 95 ps) / 3,745 ps = 47.5% (for low
boundary)
(T/2 + DCD) / T = (3,745 ps/2 + 95 ps) / 3,745 ps = 52.5% (for high
boundary)
