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:
To calculate the DCD as a percentage:

The DCD specification is based on a no logic array noise condition.
(T/2 – DCD) / T = (3745ps/2 – 95ps) / 3745ps = 47.5% (for low
(T/2 + DCD) / T = (3745ps/2 + 95ps) / 3745ps = 52.5% (for high
