Cyclone II Device Handbook, Volume 1
For DDIO outputs, you can calculate actual half period from the
following equation:
For example, if the DDR output I/O standard is SSTL-2 Class II, the
maximum DCD for a –5 device is 155 ps (refer to
frequency is 167 MHz, the half-clock period T/2 is:

Table 5–57. Maximum for DDIO Output on Row Pins with PLL in the Clock
Path
Row Pins with PLL in the Clock Path
Actual half period = ideal half period – maximum DCD
T/2 = 1/(2* f )= 1 /(2*167 MHz) = 3 ns = 3000 ps
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.
