Here is an example for calculating the DCD as a percentage for an SDR
output on a row I/O on a –6 device:
If the SDR output I/O standard is SSTL-2 Class II, the maximum DCD is
65 ps (refer to
period T is:
To calculate the DCD as a percentage:

(Part 1 of 2)
Column I/O Output Standard
T = 1/ f = 1 / 167 MHz = 6 ns = 6000 ps
(T/2 – DCD) / T = (6000 ps/2 – 65 ps) / 6000 ps = 48.91% (for low
boundary)
(T/2 + DCD) / T = (6000 ps/2 + 65 ps) / 6000ps = 51.08% (for high
boundary
Row I/O Output Standard
The DCD specification is characterized using the maximum drive strength
available for each I/O standard.
Numbers are applicable for commercial, industrial, and automotive devices.
